Bayesian Channel Estimation in Chaos Based DS-CDMA System

This paper proposes maximum a priori (MAP) channel estimation technique in chaos based code division multiple access (CDMA) system. Two different cases are considered for estimating the fading channel. In the first case, channel coefficients are estimated with the help of chaotic sequences. In the second case estimation is performed without including the chaotic sequence in the estimation algorithm. Simulation results shows that the MAP estimation algorithms performance is better for the first case.
