摘要

我们考虑了有和没有多输入多输出(MIMO)天线系统的前向链路(基地到移动)共享信道的性能。对一种以时分多路复用(TDM)方式为用户服务的CDMA共享信道进行了分析和仿真。插槽结构和芯片速率基于宽带CDMA标准。通过链路级仿真比较了两种不同接收机的性能:线性最小均方误差(MMSE)和非线性(turbo/迭代)MMSE。此外，还比较了天线阵权值反馈前后MIMO的性能。

CDMA receiver performance for multiple-input multiple-output antenna systems

We consider the performance of a forward link (base-to-mobile) shared channel with and without a multiple-input multiple-output (MIMO) antenna system. A CDMA shared channel is analyzed and simulated for which users are served in a time division multiplexed (TDM) manner. The slot structure and chip rate are based on the wideband CDMA standard. Link-level simulations are presented to compare the performances of two different receivers: linear minimum mean-square-error (MMSE), and nonlinear (turbo/iterative) MMSE. In addition, MIMO performance is compared with and without antenna array weight feedback.
