Abstract: In this paper, a novel Direct Sequence/Spread Spectrum (DS/SS) communication scheme is proposed which exploits the 2-D complex chaotic Ikeda Map (IM) as the spreading sequence. With the proposed system, we can mitigate multiple access Interference (MAI) by selecting the codes with appropriate cross correlation characteristics. The performance of the proposed complex spreading DS/SS system is assessed and demonstrated in multiuser environment by means of computer simulation. Studies reveal that the new system significantly outperforms the Gold code based DS/SS-BPSK system.
