空时CDMA多用户信号检测

本文利用最小均方误差(MMSE)和最大似然(ML)准则,推导了空时CDMA多用户检测算法,分析了空时多用户检测与单用户检测的关系,并提出一种空时CDMA多用户检测接收机结构.计算机仿真结果说明了本文提出的空时CDMA多用户检测算法,与单用户检测方法相比其误码性能有相当的改进.

Space-time Multiuser Detection in CDMA Systems

Space-time multi-user detection for CDMA communication systems is considered in this paper The multi-user receiver structure is Proposed on the basis of minimal mean square rule and ML rule. And a new space-time multi-user algorithm is derived. The relation of single user detection and multi-user detection is also analysized Computer simulations illustrated that the performance of the algorithms proposed is much better than that or traditional single-user detection .
