| 摘 要： | 主要介绍三种面向非正交多脉冲调制(NMM)系统的非相干最小均方误差(MMSE)多用户检测器,它们均采用MMSE预滤波器(per-filter),但分别满足三种不同的非相干判决准则。其中最简单的判决准则是最大(MM)准则,另外两种则需要考虑MMSE滤波后的残余多用户干扰(MAI)的二阶统计量。然后介绍一种基于随机估计方法的盲自适应算法。最后对这三种判决准则进行性能分析。 |

| Abstract: | This paper mainly covers three non-coherent MMSE multiuser receivers, which have a common MMSE pre-filter and followed by one of the three different decision rules respectively. The simplest one is maximum magnitude rule and the others consider the second-order statistics of the residual MAI. A blind adaptive algorithm based on the stochastic approximation is discussed and then the performances of these detection rules are analyzed. |
| Keywords: | blind adaptive receiver Code-Division Multi-Access Minimum Mean-Square Error non-coherent decision multiuser detection |
