Principles of military communication systems

This book is devoted to an analytical study of those aspects of communication theory which have special relevance to military systems. The book is intended for graduate students and practicing engineers with a background in communication theory. Aspects of communication warfare are considered, taking into account power and propagation, analog communications, digital communications, and pulsed jamming. Pseudonoise spread-spectrum systems are examined, giving attention to principles, pseudonoise sequences, the concealment of pseudonoise waveforms, error probabilities in presence of interference, jamming, code synchronization, pseudonoise networks, and burst-communication systems. Frequency hopping is discussed along with interception, adaptive antenna systems, and cryptographic digital communications. Topics reviewed in an appendix are related to derivations of conditional bit error probabilities for frequency-shift keying, and the noncentral chi-squared distribution.
