PERFORMANCE ANALYSIS OF CHAOS BASED INTERLEAVER IN IDMA SYSTEM

Chaos are wide spread in nature, furthermore its use in the field of communication drew attention in early 90's and recently chaos based spread spectrum (SS) communication become an interesting area of research. Based on the research; this paper presents the study of chaos theory and then leads the discussion towards the chaos based SS system. Interleave Division Multiple Access (IDMA) based spread spectrum has been considered for performance analysis. First it reviewed the role of chaos in spread spectrum communication and then discussion extends to chaos based IDMA, which is relatively a new and promising technique in this area. Simulation results verify that chaos based IDMA can achieve good BER performance as well as offers less computational complexity.
