Yewen Cao · Computer Engineering and Applications Journal · 2009
In MC-CDMA uplink,Multi-Access Interference(MAI) is one of the major performance degradation factors.In this paper,a multi access interference cancellation algorithm based on received signal power ordering and QR decomposition is proposed. Simulation results show that,the proposed algorithm outperforms traditional successive interference cancellation algorithm in terms of Bit Error Rate(BER).Meanwhile,the complexity of the proposed algorithm is lower.
