Performance of DS-CDMA in WiMax SUI Channel
Lei Chen · Communications technology · 2008
In WiMax SUI channel, conventional per carrier minimum mean square error(PC-MMSE) and a novel linear per user minimum mean square error (PU-MMSE) detection techniques for direct sequence code-division multiple access(DS-CDMA)with frequency domain equalization(FDE)are presented in this paper. It is shown by computer simulation that DS-CDMA with PU-MMSE FDE in WiMax SUI channel obviously outperforms the DS-CDMA with conventional MMSE FDE.
