Provides a thorough discussion of the orderability of a group. The book details the major developments in the theory of lattice-ordered groups, delineating standard approaches to structural and permutation representations. A radically new presentation of the theory of varieties of lattice-ordered groups is offered.;This work is intended for pure and applied mathematicians and algebraists interested in topics such as group, order, number and lattice theory, universal algebra, and representation theory; and upper-level undergraduate and graduate students in these disciplines.;College or university bookstores may order five or more copies at a special student price which is available from Marcel Dekker Inc, upon request.

Advanced Signal Processing for Communication Systems consists of 20 contributions from researchers and experts. The first group of chapters deals with the audio and video processing for communications applications, including topics ranging from multimedia content delivery over the Internet, through the speech processing and recognition to recognition of non-speech sounds that can be attributed to the surrounding environment. The book also includes sections on applications of error control coding, information theory, and digital signal processing for communication systems like modulation, software-defined radio, and channel estimation. Advanced Signal Processing for Communication Systems is written for researchers working on communication systems and signal processing, as well as telecommunications industry professionals.

Recent advancements in communication systems performance have been only possible because of digital signal processing applied in all areas of communication systems development and implementation.

Significant attention is given to orthogonal frequency division multiplexing (OFDM) in its various forms, e.g. HIPERLAN, IEEE 802, 11 a. Aspects of OFDM technology covered include novel forms of modulation and coding, methods of reducing in-band and out-of-band spurious signal generation, and means of reducing the peak-to-average power ratio of an OFDM waveform. In these contributions, a key objective is to return the inherent implementational simplicity of the OFDM technique while enhancing its performance relative to single carrier systems.
Digital signal processing for second and third generation systems is represented in the book as well. The topics cover both theoretical issues like spreading sequence design and implementation issues of 3G user equipment modem, and MMSE receivers for CDMA systems. A useful comparison of complexity of channel estimation, equalization and decoding for GSM receivers is discussed, too.
The book also includes sections on applications of error control coding, information theory, and digital signal processing for communication systems like modulation, software-defined radio, and channel estimation.

This book constitutes the refereed proceedings of the 6th International Conference on Cryptography and Coding held at the Institute of Mathematics and its Applications (IMA) in Cirencester, UK, in December 1997. The 35 revised full papers presented emphasize the links and commonality between the underlying mathematical bases and algorithmic foundations of cryptography, error control coding and digital signal processing devices available today. Besides classical crypto topics, other issues concerning information transmission and processing are addressed, such as multiple-access coding, image processing, synchronization and sequence design.

This book contains papers presented at a special Symposium, Communications and Coding, held to celebrate the 60th birthday of Professor Paddy Farrell on 25th January 1998. Professor Farrell has made an outstanding contribution to the fields of digital communications in general, and error control in particular, with many significant publications and invited papers. The themes of the Symposium reflect Professor Farrell's specialist interests over the years: error control coding, encryption and sequence design, decoding of error control codes, signal processing in communications systems and communications systems and networks.
