Polyakov I. Estimation of a noice stability ensembles of address codes for CDMA-systems.

Dissertational work is devoted to development of methods of an estimation of quality of ensembles address code sequences for CDMA-systems. In the dissertation new techniques of the numerical analysis of stability of address code sequences to distortions in a channel are developed and investigated. The basic difference of the offeredtechnique from known will consist in inclusion in consideration of all important factors which influence the transferred signal in a liaison channel, and also features of ensembles of address code sequences. The offered technique allows to prove a choise of the most rational on a noise stability of CDMA-systems for development of telecommunications in Ukraine. On the basis of the developed technique the program complex is developed and research the stability of the most widespread ensembles of address codes to distortions in the channel is lead.
