摘要

我们在蜂窝宽带引擎处理器上提出了具有LTE参数的12倍12 MIMO-OFDM(12个数据流)的时间关键核心功能的实时实现。MMSE均衡器矩阵更新间隔为1毫秒(高移动性)，CPU利用率低于50%。并发双向处理(预编码和后处理)在此更新速率下是可行的。

12x12 MIMO-OFDM realtime implementation for 3GPP LTE+ on a Cell Processor

We present a realtime implementation of the time-critical core functions for 12 times 12 MIMO-OFDM (12 data streams) with LTE parameters on a cell broadband engine processor. An MMSE equalizer matrix update interval of 1 ms (high mobility) is achieved with less than 50% CPU utilization. Concurrent bidirectional processing (precoding and postprocessing) is shown to be feasible with this update rate.
