Perspective directions of development of information transfer systems, used complex signals with a large base, are considered. Benefits of telecommunication systems with a code extension of spectrum are discussed. The way of information transmission with code separation of abonent channels on the base of a set of chaotic codes is realized and a digital generator of chaotic codes is de­veloped. Experiments on studying the influence of a chaotic code delay on the process of information separation by a convolution of the accepted signal are carried out. It is shown that a digital telecommunication system with a spectrum extension and dynamical change of chaotic codes possesses high noise-stability and reticence and provides reliable and confidential transmission of mes­sages under conditions of complex electromagnetic circumstances.
