Spread Spectrum in Communication PDF

The book is devoted to advanced radiocommunication, discussing the merits and operational aspects of spread spectrum signalling. The book starts by comparing spread spectrum modulation and conventional modulation methods, and then discusses demodulation, which requires both special acquisition and synchronisation techniques. The electronic warfare scenario is introduced, discussing the principles of various spreading techniques and possible countermeasures. The coding for bandwidth spreading in a direct sequence spread spectrum system is treated by discussing the most common codes and their different figures of merit with respect to multipath, code division multiplexing and signal concealment. The book also illustrates the possible benefits, as well as limits to the use of new hardware technology to accomplish the various functions necessary fo successful operation of a spread spectrum system. The effect of the propagatior environment on spread spectrum is treated both analytically and through reportec experiments and simulations. Finally the book considers the task of designing complete communication network and discusses the usefulness and technology fo additional interference suppressing techniques suitable to work with spread spectrum systems.
