EFFICIENCY OF USE TIME SIGNALS IN BROADBAND TRANSMISSION SYSTEMS WITH DIRECT SEGUENCE SPREAD SPECTRUM

Abstract

Counteraction to facilities of unauthorized division and radiotechnical secret service is a major task at the construction of confidential communication networks, therefore development and research of methods transmissions are actual that allow to increase secrecy of transferrable signals in a communication channel. It is suggested to complicate the structure of transferrable signals for the increase of structural and informative secrecy. One of ways of this problem decision is application of timer signalsthat allowto create the different great numbers of alarm constructions. Such properties of signals are especially important for development of alarm constructions with a changeable structure. The method of synthesis of the broadband systems of transmission is offered on the basis of timer signals and pseudorandom sequences using direct expansion of signal spectrum. The features of cross-correlation reception of broadband timer alarm constructions are considered. Possibilities of increase of structural and informative secrecy of communication network are shown with the code division of signals.
