摘要
对于天线阵周期扩频CDMA系统,我们提出了三种线性约束最小输出能量盲空时多用户检测器MOE、MOECapon和MOEMMSE。由于利用了时域扩频码信息,MOE和MOE Capon方法对信道的估计优于MMSE方法。MOEMMSE方法的输出信干噪比接近MMSE方法。
For array periodic spreading CDMA System, three optimal linear constraint minimum output energy spatial temporal multiuser detectors, MOE, MOE Capon and MOEMMSE, are proposed. The performance of channel of temporal spreading code is superior over MMSE method due to the availability of temporal spreading code. The output SINR of the proposed MOEMMSE algorithm approaches to that of optimal MMSE spatial temporal multiuser algorithm.
