| 摘 要： | 基于最小平均峰度(LMK)准则,提出了一种适用于同步直扩码分多址(DS/CDMA)系统多径慢衰落信道中的盲自适应多用户检测算法.这种算法基于高阶统计量特性,算法复杂度相对较低.仿真结果表明,该算法的稳态性能与子空间自适应多用户检测算法相当,是一种较好的多用户检测算法,有一定的实际应用价值.

| Abstract: | In this paper, a novel linear blind adaptive multiuser detection is proposed, based on LMK Criterion in Multipath fading channels and in synchronous DS/CDMA system. Analysis shows that this algorithm satisfies the decorrelating conditions. The new algorithm reduces complexity remarkably compared with the classical SVD subspace algorithm. Simulation results illustrate that the new algorithm can offer stable convergence and good detection performance. |
