Performance analysis of Spread Spectrum based Communication Systems in interference prone environment

SAMEER-Centre for Electromagnetics has developed both Direct Sequence (DS) and Frequency Hopping (FH) based Spread Spectrum (SS) Communication systems for different applications. The DS and FH systems adopt different methodology for rejecting the narrow band interference. This paper describes the performance of both DS and FH based spread spectrum systems and the mechanism of interference rejection under interference prone environment. Successful design of SS systems is evaluated in terms of level of interference signals the system can tolerate and continue to offer the same system performance with acceptable Bit Error Rate (BER). The features, interference rejection properties of both DS and FH communication systems and selection of appropriate system for an application are highlighted in this paper.
