| Abstract: | The quasi orthogonal characteristics of chaotic vectors used in conventional chaos based DS CDMA system leads to MAI. The effect of MAI deteriorates the performance of the multi-user communication system. Inorder to eliminate the effect of MAI we propose a scheme which uses orthogonal chaotic vector as spreading to modulate the message data. At the receiver a simple correlator type detector is used. Analytical expressions for BER is derived for the case of AWGN channel and compared with that of simulation results. |
