577 pages; $79.95

This mobile communications handbook includes technologies ranging from cordless telephones, digital cellular radio and evolving personal communications systems to wireless data and networks. Various aspects of modulation, digital communications and mobile communications applications are covered by 52 experts. The authors provide personal insights about the future of the various fields covered. The 35 articles offer an overview of each topic that is a stand-alone treatment of the subject.

The handbook is separated into two parts. Section I covers basic principles, including articles on analog modulation, sampling pulse code modulation, baseband signaling and pulse shaping, channel equalization and line coding. Also included are papers on echo cancellation, pseudonoise sequences, optimum receivers, forward error-correction coding, spread spectrum communications, diversity techniques, digital communications system performance and standards-setting bodies.

Section II includes overviews of wireless personal communications and mobile radio, as well as articles on base station subsystems, access methods, location strategies for personal communications services, cell design principles, microcellular radio communications, fixed and dynamic channel adjustment, propagation models and power control. The section also contains papers on second-generation systems; the Pan-European Cellular System; the IS-54 digital standard; code-division multiple access technology and the IS-95 North American standard; the Japanese cellular standard; CT-2, the British cordless telephone standard; Digital European Cordless Telephones; the race program; half-rate standards; modulation methods; wireless local area networks; and wireless data.

Each article is an independent contribution designed to bring the reader up to date. Although communications theory is presented adequately, this handbook focuses on current and evolving applications of mobile communications technology. The numerous references provided by each author will aid the reader in further studies.

Hilbert Transforms in Signal Processing

Signal processing is one of the fastest growing areas in modern technology. Today’s sophisticated signal processors are microelectronics based and are used in telecommunications, radio location systems, transportation and medical equipment, optical and radioastronomy systems, and anywhere that data must be transmitted from one point to another. The signal processing algorithms are implemented using sophisticated software and comprise various integral transformations including Fourier, Laplace and Hilbert. This book describes in detail the theory and selected applications of the Hilbert transformation, which serves as a theoretical basis of the complex notation of signals.

The book opens with the one-dimensional Hilbert transformation and compares it to Laplace transformations, laying the groundwork for the complex theoretical analysis that follows. Chapter 2 presents several Hilbert transformation properties and describes some useful applications. Chapter 3 deals with distributed signals and the concepts of the delta and unit step functions for which the Fourier transform exists. Chapter 4 introduces the discrete Hilbert transformation for applications involving digital signals. Digital Hilbert filters are described, and the design methods for these devices are detailed in Chapter 5.

Chapter 6 is devoted to analog modulation and the role of the Hilbert transformation in defining single-sideband modulation. Applications of the Hilbert transformation in signal and system theory are presented in Chapter 7, including applications in sampling theory and random noise realizations. The final two chapters discuss multidimensional complex signals and applications of both Hilbert and Fourier transformations in this area.

In spite of the highly complex subject, this book is well written and provides a clear explanation of the topic. For engineers involved in modern signal processing technology and its applications, this book is a fine reference text.
