Abstract

Multi-Carrier Code Division Multiple Access is regarded as one of the main candidates for 4G broadband wireless services. It combines the benefit of robustness to the multipath effects in OFDM systems and the benefit of high privacy and security in CDMA systems. However, a problem arises in the detection of transmitted information due to the effect of noise, fading and other multipath effects. In this paper, a solution is proposed to this problem by introducing the quantum genetic algorithm based MC-CDMA detector. The performance of the proposed detector was investigated and compared with QGA based MIMO-OFDM detector proposed in previous work. The simulation results showed that the proposed QGA based MC-CDMA detector was better in BER performance than QGA based MIMO-OFDM detector showing a performance closer to the optimum.
