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.
