In multichannel data transmission systems noise-like signals, generated on the basis of derivatives of the Walsh function are used. The article examines the correlation properties of derivatives of Walsh functions with generating functions in the form of perfect binary lattices, which make it possible to provide the necessary data synchronization when receiving signals. Also, 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 and to protect against unauthorized access.
