Correlation delay shift keying based chaotic MIMO communication system

Abstract

In recent years chaotic communication systems have emerged as an alternative solution to conventional spread spectrum systems. The security of chaos communication system is superior to other digital communication system, because it has characteristics such as non-periodic, wide-band, non-predictability, easy implementation and sensitive initial condition. This paper makes a primary contribution to evaluate the BER performance of Chaos MIMO Communication system. The different maps that have been considered are Tent map, Boss map, Henon map and logistic map. The modulation scheme that has been considered is CDSK in presence of AWGN channel.
