Performance Comparison of FH-CDMA Scheme Using Chaotic Sequences over Fading Channels
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 5
Abstract
In this work, the performance analysis of FH-CDMA scheme in terms of bit error probability (BEP) Vs number of simultaneous users over three different channels i.e. AWGN, Rician and Rayleigh channels is presented. The prime and chaotic sequences were used in this work as spreading sequences to the FH-CDMA scheme resulting in prime/FH-CDMA and chaotic/FH-CDMA scheme respectively. Bit Error Probability against the number of simultaneous users over AWGN, Rician and Rayleigh fading channels are plotted for prime/FH-CDMA scheme and chaotic/FH-CDMA scheme and compared. Chaotic sequences have good correlation properties and then can be used as address sequences in spread spectrum communication. Simulation results showed that chaotic/FH-CDMA scheme can accommodate more number of simultaneous users with lower Bit Error Probability than compared to prime/FH-CDMA scheme.
