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).

In 1999,t he Wireless Symposiumwas expanded to include atutorial course. This activity proved populara nd was continued in 2000.

This work presents a range of topics in wireless communications, including perspectives from both industry and academia. The book serves as a reflection of emerging technologies in wireless communications and features papers from well-known authors on the subject. It is divided into six sections. The first five of these cover the following topics: propagation and channel modelling (4 papers); antennas (6 papers); multiuser detection (3 papers); radio systems and technology (4 papers); and wireless data (3 papers). The last section contains papers on areas of significant interest. The text should be useful as a reference source for graduate students, postgraduate researchers, academics and anyone working in the research aspect of the wireless communications industry.

This text presents a broad range of topics in wireless communications, including perspectives from both industry and academia. The book serves as a reflection of late-1990s research thrusts in wireless communications, an area which continues to grow as the industry strives to provide a wider range of services with greater reliability and at lower cost. The book is organized into four sections. Section I focuses on propagation and smart antennas with emphasis on measurements, modelling and simulation. Section 2 is devoted to the 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. The volume should serve as a useful reference source and may be used as a text for advanced courses on the subject.

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.

Ziemer and Tranter provide a thorough treatment of the principles of communications at the physical layer suitable for college seniors, beginning graduate students, and practicing engineers. This is accomplished by providing overviews of the necessary background in signal, system, probability, and random process theory required for the analog and digital communications topics covered in the book. In addition to stressing fundamental concepts, the seventh edition features sections on important areas such as spread spectrum, cellular communications, and orthogonal frequency-division multiplexing. While the book is aimed at a two-semester course, more than enough material is provided for structuring courses according to students need and instructor preference.

Wireless personal communications, or wireless as it is now being called, has arrived. The hype is starting to fade, and the hard work of deploying new systems and services for personal communications is underway. In the United States, the FCC propelled the wireless era from infancy to mainstream with a $7.7 billion auction of 60 MHz of radio spectrum in the 180011900 MHz band. With the largest single sale of public property in the history of mankind mostly complete, the resources of the entire world are being called upon to develop inexpensive, rapidly deployable wireless systems and sub­ scriber units for an industry that is adding s\lbscribers at greater than 50% annual rate. This growth is commonplace for wireless service companies throughout the world, and in the U.S., where as many as 7 licensed wireless service providers may be competing for cellularlPCS customers within the next couple of years, differentiators in cost, qual­ ity, service, and coverage will become critical to customer acceptance and use. Many of these issues are discussed in the papers included in this book.
