摘要

对预编码选择算法进行研究。提出了一种基于小区参考信号的预编码矩阵索引估计算法。以类似的方式进行了模拟。该算法能有效区分MIMO的空间特征，解决了不经过预编码的CRS不能反映信道反馈信息的局限性。结果表明，该算法的性能更接近理想的预编码反馈方案。

Precoding Matrix Index Estimation Algorithm in LTE-A System

Conduct research on precoding select algorithm. A precoding matrix index estimate algorithm based on cell reference signal (CRS) was proposed. Simulation had been conducted in a comparable manner. This algorithm can distinguish the MIMO space characteristic effectively and solved the limitation that CRS not to pass through the precoding could not reflect the channel feedback information. Results show that the proposed algorithm performance is closer to ideal precoding feedback scheme.
