Abstract EN
The use of chaotic sequences which have low cross-correlation can be useful for spreading the direct sequence code division multiple access (DS-CDMA) system.
In this paper, a chaotic multiple access communication system based on Orthogonal Chaotic Vector (OCV) generated from Rikitake system has been proposed.
The simulation results proved that the performance of the proposed system is almost the same regardless of the number of users in Additive White Gaussian noise AWGN channel.
The results also showed that for single user transmission and at bit-error-rate of 10-3, the proposed system can achieve signal-to-noise ratio gains of 7 dB and 9 dB in over traditional DS-CDMA in AWGN and Rayleigh fading channels respectively.
While for 4 users transmission and at bit-error-rate of 10-3, the proposed system can achieve signal-to-noise ratio gains of 7 dB and 9 dB in over traditional DS-CDMA in AWGN and Rayleigh fading channels respectively.
