Increasing the efficiency of the application of discrete Walsh signals in telecommunication systems

Abstract

The paper analyzes correlation functions of discrete Walsh signals obtained on the basis of Walsh functions. The advantage of these signals is the zero value of the main petal of the cross-correlation function (CCF), which indicates their orthogonality. But a significant drawback of these signals is a significant level of unwanted side lobes of both the CCF and the autocorrelation function (ACF). Based on the analysis of the features of CCF and ACF of discrete Walsh signals, a method of increasing the efficiency of their use in telecommunication systems (TCS) is proposed.
