Broadband Wireless Access


Book Description

Bing (satellite and hybrid communication networks, U. of Maryland) discusses the design and development of wireless access protocols, emphasizing how such protocols can efficiently support disparate classes of multimedia traffic. After introducing and surveying the evolution of wireless access protocols, he describes many important protocols that are deployed or experimented with in various broadband wireless environments, such as asynchronous transfer mode, satellite networks, mobile cellular and personal communications systems, local loops, and local-area and home networks. Seeking a broad audience ranging from novices to veterans who are undertaking research in the area, he does discuss engineering aspects but focuses on the physical understanding and keeps the mathematics to a minimum.

Telecommunications Measurements, Analysis, and Instrumentation


Book Description

A rare text dedicated to high-performance measurement techniques in modern communications. It describes high performance measurement techniques for digital communications and digital signal processing in radio and microwave systems, wire line channels, as well as measurements for analog communications channels. AUTHOR'S COMMENTS The purpose of this book is to present the engineering considerations necessary for the comprehension of modern telecommunication measurement and related instrumentation and analysis techniques. I wish to emphasize that this is not an academic book in the sense of analytical communications or measurement theory. Rather, it stresses the measurements, experimental analysis and instrumentation problems related to communications systems. PUBLISHER'S COMMENTS This book provides a strong foundation for understanding the special problems associated with testing modern communications systems. Its original publication anticipated the needs of communications engineers, setting a foundation for current work. The book's continued availability assures that new engineers will have access to a key reference text in this important area of technology.




Bandwidth-Efficient Digital Modulation with Application to Deep Space Communications


Book Description

An important look at bandwidth-efficient modulations with applications to today's Space program Based on research and results obtained at the California Institute of Technology's Jet Propulsion Laboratory, this timely book defines, describes, and then delineates the performance (power and bandwidth) of digital communication systems that incorporate a wide variety of bandwidth-efficient modulations appropriate for the design and implementation of space communications systems. The author compares the performance of these systems in the presence of a number of practical (non-ideal) transmitter and receiver characteristics such as modulator and phase imbalance, imperfect carrier synchronization, and transmitter nonlinearity. Although the material focuses on the deep space applications developed at the Jet Propulsion Laboratory, the presentation is sufficiently broad as to be applicable to a host of other applications dealing with RF communications. An important contribution to the scientific literature, Bandwidth-Efficient Digital Modulation with Application to Deep Space Communications * was commissioned by the JPL Deep Space Communications and Navigation System Center of Excellence * highlights many NASA-funded technical contributions pertaining to deep space communications systems * is a part of the prestigious Deep Space Communications and Navigation Series The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.
