Performance of Multi-User DCSK Communication System Over Multipath Fading Channels
The bit error rate (BER) performances of an invariant delay multiple access DCSK (IDMA-DCSK) communication system over multipath fading channels are investigated. According to central limit theorem (CLT) we evaluate the BER formula of the IDMA-DCSK over Rayleigh and Ricean fading channels respectively. A two-ray fading channel model is used to simulate the IDMA-DCSK system. The theoretical and the simulation results match closely to each other, which supports the analyses approach.
