Introduction to Spread Spectrum Communication Systems
Kamil Sh. Zigangirov · 2004
Spread spectrum (SS) technology is used in multiple access communication to increase resistance to signal interference from multiple transmission paths and to increase bandwidth efficiency. In this chapter, we describe several digital modulation techniques that are used in spread spectrum communication. In the analysis of digital modulation, we treat the signals as stationary stochastic processes. We start with a short mathematical introduction into the theory of stochastic processes and then study correlation and spectral characteristics of DS SS, FH SS and PPH SS signals.
