Особенности корреляционных свойств шумоподобных сигналов

Abstract

Тhe paper discusses the basic properties of noise signals, which are used in modern data transmission systems. It is shown, that for obtaining these signals are used pseudo-random sequence with the highest possible base. The correlation characteristics of the main types of pseudo-random sequences that are used in the construction of spread spectrum systems are considered: Barker's codes, Barker-Volinskaya’s codes and Msequences. The autocorrelation and cross-correlation functions of the signals are given. Substantiated is the possibility of applying these signals in the development of data transmission systems using noise-like signals.
