dc.description Only Abstract en_US
dc.description.abstract The article discusses the correlation properties of pseudo-random sequences (PRS) used in the formation of noise-like signals in data transmission systems with code division multiple access (CDMA). The analysis, carried out in Matlab environment, showed that correlation properties of the Walsh functions derivatives, used for generating PRS, have much better correlation characteristics than the original Walsh functions. Besides, these properties depend on the type of generating function of Walsh functions derivatives. Correlation properties of various generating functions were investigated. It was justified the advantage of using these signals in the development of CDMA systems in order to reduce the interference level of multiple access. en_US
