Abstract :
In this paper, a non coherent multiple access(MA) chaotic communication system using Orthogonal Chaotic Vectors (OCV) as spreading sequences with adaptive multi user receivers are tested and analysed. Here we consider two types of adaptive receivers 1) LMS based detector 2) CSE based detector. Theoretical equations for BER are also derived for both cases considering awgn channel. The simulation results are compared with that of theoretical results.
