Analysis of Spread Spectrum System Parameters for Design of Hidden Transmission

Abstract

A short analysis of spread spectrum communication system is performed with respect to the determination of its fundamental system parameters for transmitted signal hidden in the noise. The paper shows dependence of processing gains on the correlation circuits at the receiver side. The distance, from which the transmitter signal is hidden in noise, depends on the spread spectrum factor and the transmitted power. At a given interference power density and at a given requirement of transmitted signal hiding we can calculate the spreading factor of system. A processing gain of spread spectrum system determines a depth of signal hiding in the noise. A transmission range of spread spectrum communication system is given by the transmitted power and the processing gain of the system.
