This book introduces wireless personal communications from the point of view of wireless communication system researchers. Existing sources on wireless communications put more emphasis on simulation and fundamental principles of how to build a study model. In this volume, the aim is to pass on to readers as much knowledge as is essential for completing model building of wireless communications, focusing on wireless personal area networks (WPANs). This book is the first of its kind that gives step-by-step details on how to build the WPANs simulation model. It is most helpful for readers to get a clear picture of the whole wireless simulation model by being presented with many study models. The book is also the first treatise on wireless communication that gives a comprehensive introduction to data-length complexity and the computational complexity of the processed data and the error control schemes. This volume is useful for all academic and technical staff in the fields of telecommunications and wireless communications, as it presents many scenarios for enhancing techniques for weak error control performance and other scenarios for complexity reduction of the wireless data and image transmission. Many examples are given to help readers to understand the material covered in the book. Additional resources such as the MATLAB codes for some of the examples also are presented.
Applications of some selected soft computing methods to acoustics
and sound engineering are presented in this book. The aim of this
research study is the implementation of soft computing methods to
musical signal analysis and to the recognition of musical sounds
and phrases. Accordingly, some methods based on such learning
algorithms as neural networks, rough sets and fuzzy-logic were
conceived, implemented and tested. Additionally, the
above-mentioned methods were applied to the analysis and
verification of subjective testing results. The last problem
discussed within the framework of this book was the problem of
fuzzy control of the classical pipe organ instrument.
Recently, we proposed a completely novel and efficient way to design differential beamforming algorithms for linear microphone arrays. Thanks to this very flexible approach, any order of differential arrays can be designed. Moreover, they can be made robust against white noise amplification, which is the main inconvenience in these types of arrays. The other well-known problem with linear arrays is that electronic steering is not really feasible. In this book, we extend all these fundamental ideas to circular microphone arrays and show that we can design small and compact differential arrays of any order that can be electronically steered in many different directions and offer a good degree of control of the white noise amplification problem, high directional gain, and frequency-independent response. We also present a number of practical examples, demonstrating that differential beamforming with circular microphone arrays is likely one of the best candidates for applications involving speech enhancement (i.e., noise reduction and dereverberation). Nearly all of the material presented is new and will be of great interest to engineers, students, and researchers working with microphone arrays and their applications in all types of telecommunications, security and surveillance contexts.

Featuring real-time applications, empirical research, and vital frameworks within the field, this publication is a critical reference source for researchers, professionals, engineers, academicians, advanced-level students, and technology developers.
Coded Modulation Systems is an introduction to the subject of coded modulation in digital communication. It is designed for classroom use and for anyone wanting to learn the ideas behind this modern kind of coding. Coded modulation is signal encoding that takes into account the nature of the channel over which it is used. Traditional error correcting codes work with bits and add redundant bits in order to correct transmission errors. In coded modulation, continuous time signals and their phases and amplitudes play the major role. The coding can be seen as a patterning of these quantities. The object is still to correct errors, but more fundamentally, it is to conserve signal energy and bandwidth at a given error performance. The book divides coded modulation into three major parts. Trellis coded modulation (TCM) schemes encode the points of QAM constellations; lattice coding and set-partition techniques play major roles here. Continuous-phase modulation (CPM) codes encode the signal phase, and create constant envelope RF signals. The partial-response signaling (PRS) field includes intersymbol interference problems, signals generated by real convolution, and signals created by lowpass filtering. In addition to these topics, the book covers coding techniques of several kinds for fading channels, spread spectrum and repeat-request systems. The history of the subject is fully traced back to the formative work of Shannon in 1949. Full explanation of the basics and complete homework problems make the book ideal for self-study or classroom use.

The first two international conferences on Ultra-Wideband (UWB), Short-Pulse (SP) Electromagnetics were held at Polytechnic University, Brooklyn, New York in 1992 and 1994. Their purpose was to focus on advanced technologies for generating, radiating, and detecting UWB, SP signals, on mathematical methods, their propagation and scattering, and on current as well as potential future applications. The success of these two conferences led to the desirability of scheduling a third conference. Impetus was provided by the electromagnetics community and discussions led by Carl Baum and Larry Carin resulted in the suggestion that the UWB conferences be moved around, say to government laboratories such as Phillips Laboratory. Consequently the decision was made by the Permanent HPEM Committee to expand AMEREM '96 to include the Third Ultra-Wide Band, Short-Pulse (UWB, SP 3) with the Third Unexploded Ordnance Detec tion and Range Remediation Conference (UXO) and the HPEMINEM Conference in Albuquerque, New Mexico during the period May 27-31, 1996. Planning is now underway for EUROEM '98 in June, 1998 in Tel Aviv, Israel. Joseph Shiloh is the conference chairman. A fourth UWB, SP meeting is planned as a part of this conference and Ehud Heyman will coordinate this part of the meeting. The papers which appear in this volume, the third in the UWB, SP series, update subject areas from the earlier UWB, SP conferences. These topics include pulse generation and detection, antennas, pulse propagation, scattering theory, signal processing, broadband electronic systems, and buried targets."
Multi-point Cooperative Communication Systems: Theory and Applications mainly discusses multi-point cooperative communication technologies which are used to overcome the long-standing problem of limited transmission rate caused by the inter-point interference. Instead of combating the interference, recent progress in both academia and industrial standardizations has evolved to adopt the philosophy of "exploiting" the interference to improve the transmission rate by cooperating among multiple points. This book addresses the multi-point cooperative communication system systematically giving the readers a clear picture of the technology map and where the discussed schemes may fit. This book includes not only the theories of the paradigm-shifting multi-point cooperative communication, but also the designs of sub-optimal cooperative communication schemes for practical systems. Ming Ding is a senior researcher at Sharp Laboratories of China; Hanwen Luo is a professor at Shanghai Jiao Tong University.
Including a systematic introduction to the fundamental principles of microwave radar, this text presents an extensive discussion of radar imaging. It also features information on image superresolution, automatic target recognition, moving target indication, and space-time adaptive processing (STAP).
Grid architectures, which are viewed as tools for the integration of distributed resources, play a significant role as managers of computational resources, but also as aggregators of measurement instrumentation and pervasive large-scale data acquisition platforms. The functionality of a grid architecture allows managing, maintaining, and exploiting hetereogeneous instrumentation and acquisition devices in a unifed way by providing standardized interfaces and common work environments to their users. This result is achieved through the properties of isolation from the physical network and from the peculiarites of the instrumentation granted by standard middleware together with secure and flexibile mechanisms which seek, access, and aggregate distributed resources. This book focuses on a number of aspects related to the effective exploitation of remote instrumentation on the grid. These include middleware architecture, high speed networking in support of grid applications, wireless grid for acquisition devices and sensor networks, quality of service provisioning for real time control, and measurement instrumentation.
The increase of consumer electronics and communications applications using Radio Frequency (RF) and microwave circuits has implications for oscillator design. Applications working at higher frequencies and using novel technologies have led to a demand for more robust circuits with higher performance and functionality, but decreased costs, size and power consumption. As a result, there is also a need for more efficient oscillators. This book presents up-to-date information on all aspects of oscillator design, enabling a selection of the best oscillator topologies with optimized noise reduction and electrical performance. RF and Microwave Transistor Oscillator Design covers: analyses of non-linear circuit design methods including spectral-domain analysis, time-domain analysis and the quasilinear method;information on noise in oscillators including chapters on varactor and oscillator frequency tuning, CMOS voltage-controlled oscillators and wideband voltage-controlled oscillators;information on the stability of oscillations, with discussions on the stability of multi-resonant circuits and the phase plane method;optimized design and circuit techniques, beginning with the empirical and analytic design approaches, moving on to the high-efficiency design technique;general operation and design principles of oscillators, including a section on the historical aspects of oscillator configurations. analyses of non-linear circuit design methods including spectral-domain analysis, time-domain analysis and the quasilinear method; information on noise in oscillators including chapters on varactor and oscillator frequency tuning, CMOS voltage-controlled oscillators and widebandvoltage-controlled oscillators; information on the stability of oscillations, with discussions on the stability of multi-resonant circuits and the phase plane method; optimized design and circuit techniques, beginning with the empirical and analytic design approaches, moving on to the high-efficiency design technique; general operation and design principles of oscillators, including a section on the historical aspects of oscillator configurations.

This book introduces readers to the novel concept of variable span speech enhancement filters, and demonstrates how it can be used for effective noise reduction in various ways. Further, the book provides the accompanying Matlab code, allowing readers to easily implement the main ideas discussed. Variable span filters combine the ideas of optimal linear filters with those of subspace methods, as they involve the joint diagonalization of the correlation matrices of the desired signal and the noise. The book shows how some well-known filter designs, e.g. the minimum distortion, maximum signal-to-noise ratio, Wiener, and tradeoff filters (including their new generalizations) can be obtained using the variable span filter framework. It then illustrates how the variable span filters can be applied in various contexts, namely in single-channel STFT-based enhancement, in multichannel enhancement in both the time and STFT domains, and, lastly, in time-domain binaural enhancement. In these contexts, the properties of these filters are analyzed in terms of their noise reduction capabilities and desired signal distortion, and the analyses are validated and further explored in simulations.
Designers of wireless networks face a problem which is multidimensional in nature, where issues of multiaccess, radio propagation, antennas, mobility and teletraffic all need to be understood and simultaneously addressed in order to create a properly functioning system. This book does not merely concentrate on one of these issues but takes a broader view, and presents a mix of papers addressing systems and networking issues. Multiaccess, Mobility and Teletraffic: Advances in Wireless Networks addresses fundamental theoretical issues about future wireless networks, such as capacity improvements theoretically attainable from spread spectrum systems, and practical concerns associated with current networks such as signalling, implementation of GSM and CDMA networks, and implementation of packet data services over wireless networks. As well as the papers looking at specific technologies, this book contains a number of papers discussing more generic problems in mobile networks, such as issues associated with handoff, resource management, frequency reuse, mobility, signalling and wireless packet networks. Multiaccess, Mobility and Teletraffic: Advances in Wireless Networks covers a broad range of issues associated with wireless networks and provides a very interesting snapshot of the current state-of-the-art. It will be of interest to all researchers and practitioners working in the field of wireless communications and networks.

This book was undertaken to provide a text and reference on the theory and practice of the FFT and its common usage. This book is organized in only four chapters, and is intended as a tutorial on the use of the FFf and its trade space. The trade space of the FFT is the parameters in its usage and the relationships between them - the sampie rate, the total number of points or the interval over which processing occurs in a single FFf, the selectivity of tuning to a given frequency over signals out-of-band, and the bandwidth over which a signal appears. The examples given in this text are in FORTRAN 9512003. FORTRAN 2003 was frozen as a standard while this work was in progress. The listings given here are intended as an aid in understanding the FFT and associated algorithms such as spectral window weightings, with the goal of making the best of them more accessible to the reader. The code I use here provides a simple bridge between the material in the text and implementation in FORTRAN 2003, C++, Java, MATLAB (c), and other modem languages. The examples are sufficiently simple to be translated into older languages such as C and FORTRAN 77 if desired.
