Electrical and computer engineers need to understand the most current technologies in the field. In order to provide the latest information, the sixth edition presents a new chapter that explores the principles of digital data transmission without the complicating factor of performance in noise. It exposes readers to digital data transmission techniques earlier in the book so that they can appreciate the characteristics of digital communication systems before learning about probability and stochastic processes. They'll also find expanded forward error correction code examples and new MATLAB problems. Electrical and computer engineers will benefit from this completely up-to-date resource.

th Thepapers appearing in this book were originally presented at the 8 Virginia Tech/MPRG Symposium on Wireless Personal Communications. This symposium, whichi s an annual event for Virginia Tech and MPRG, was held June 10 12, 1998 ont he Virginia Tech campus in Blacksburg, Virginia. The symposium brings together l eaders from industry and academia to discuss the exciting future of wireless and current research trends. The symposium has been an important part of MPRG's activities since the inception ofthe group in 1990. As can be seen fromt heT able of Contents, the papers included in this book are divided into six sections. The first five of these correspond to s ymposium sessions and aredevoted to the following topics: Smart Antennas and Diversity, Propagation, InterferenceCancellation, Equalization, and Modulation, Coding and Networking. These session titles reflectcurrent research thrusts as the wireless community strives to enhance the capabilities of wirelesscommunications. This year an added feature oft he symposium was the inclusion of externally contributed poster papers. Ten ofthese poster papers are included in thisb ooka sthe sixth section. The first group of contributions, c onsisting of five papers, relateto smart antennas and diversity. The first paper, Effects of Directional Antennas with Realizable Beam Patterns on the Spaced Time Correlation, byT . B. Welch, M. J.

Wireless Personal Communications: Improving Capacity, Services and Reliability presents a broad range of topics in wireless communications, including perspectives from both industry and academia. The book serves as a reflection of current research thrusts in wireless communications, an area which continues to grow at a rapid rate as the industry strives to provide a wider range of services with greater reliability and at lower cost. Wireless Personal Communications: Improving Capacity, Services and Reliability is organized into four sections. Section I focuses on propagation and smart antennas with emphasis on measurements, modeling and simulation. Section 2 is devoted to the important subject of Code Division Multiple Access (CDMA) systems with coverage of bit error rate calculations, interference cancellation, frequency estimators and acquisition schemes. Section 3 covers networking and multiple-access issues such as mobility tracking, Markov analysis of random access protocols, and the design and development of a prototype system to access Low Earth Orbiting (LEO) satellites. Section 4 presents software radio technologies, including wideband software-definable base station technology, space-borne processing technology for mobile communications systems, filter design, universal cordless telephone transceivers using DSP, a method for predicting nonlinearities for an RF power amplifier, MAP symbol detection of CPM bursts, and unification of MLSE receivers. Wireless Personal Communications: Improving Capacity, Services and Reliability serves as an excellent reference source and may be used as a text for advanced courses on the subject.

th The paperspresented in this book wereoriginally presented att he 10 Virginia Tech/MPRG Symposium on Wireless Personal Communications, whichw as held ont heVirginia Tech campus June 14 16,2000. Thisyear's Symposium was sponsored byVirginia Tech's M obile and Portable Radio Research Group (MPRG), the Virginia Tech D ivision ofC ontin uing Education, andthe MPRG Industrial Affiliates Program. TheIE EE Virginia Mountain Section and the Virginia Tech Joint Student Chapter ofthe IEEE Communications andVehicular Technology Societies provided technical co sponsorship. Much oft he success ofo ur annual symposium,a s well as the success of MPRG's research and educationprogram, are directlydue to the support of our industrial affiliates. The support that is provided byt he industrial affiliates program allows MPRG to serve thew irelesscommunity through research, education, andoutreach activities. MP RG's industria l affiliates include the following organizations: AnalogD evices, Inc. , AnarenMicrowave, Inc. , theA rmyResearch Office, AT&T Corporation, BAE Systems, BellSouth Cel lular Corporation, Comcast Cellular Communications, Inc. , Da tum, Inc. , Ericsson, Inc. , Grayson Wireless, Hughes Electronics Corporation, ITTIndustries, LGIC, Inc. , Lucent Technologies, Inc. , Motorola, Inc. , Nokia, Inc. , Nortel Networks, Qualcomm, Inc. , Raytheon Systems Company, Samsung Advanced Institute of Technology, Southwestern Bell, Tantivy Communications, Inc. , Tektronix, Inc. , Telcordia Technologies, Texas Instruments, andWavtrace, Inc. In 1999,t he Wireless Symposiumwas expanded to include atutorial course. This activity proved populara nd was continued in 2000.

th The papers appearing in this book were originally presented at the 9 Virginia Tech/MPRG Symposium on Wireless Personal Communications. The Symposium on Wireless Communications, which is an annual event for Virginia Tech, was held on June 2-4, 1999. The 1999 symposium was co-sponsored by MPRG, the Division of Continuing Education, University International Programs, and the MPRG Industrial Affiliate Sponsors. Much of the success of our annual symposium, as well as the success of MPRG's research program, is due to the support of our industrial affiliates. Their support allows us to serve the wireless community through research, education and outreach programs. At the time of the 1999 symposium, the MPRG affiliates program included the following organizations: Army Research Office, AT&T Corporation, Bellsouth Cellular Corporation, Comcast Cellular Communications, Inc. , Datum, Inc. , Ericsson, Inc. , Grayson Wireless, Hewlett-Packard Company, Honeywell, Inc. , Hughes Electronics Corporation, ITT Industries, Lucent Technologies, Motorola, National Semiconductor, Nokia, Nortel Networks, Qualcomm, Inc. , Radix Technologies, Inc. , Salient 3 Communications, Samsung Advanced Institute of Technology, Southwestern Bell, Tantivy Communications, Tektronix, Inc. , Telcordia Technologies, Texas Instruments, TRW, Inc. , and the Watkins-Johnson Company As can be seen from the Table of Contents, the papers included in this book are divided into six sections. The first five of these correspond to symposium sessions, and cover the following topics: Propagation and Channel Modeling (4 papers), Antennas (6 papers), Multiuser Detection (3 papers), Radio Systems and Technology (4 papers), and Wireless Data (3 papers).
