摘要

提出了一种基于天线选择的MIMO系统衰落信道时反转STBC信道估计方法。该方案依赖于从所有四个可能的天线中选择最佳的两个天线。然后提出了一种基于AS-TR-STBC的MIMO信道估计方法。该方法是一种将天线选择和时反转STBC相结合的多径衰落信道估计方法。仿真结果表明，在合理考虑有效天线功率的情况下，该方法优于其他方法。

A Simple Channel Estimate Method Of AS-TR-STBC System over Multipath Fading Channels

This paper proposes a time-reversal (TR) STBC channel estimate method based on antenna selection over MIMO system fading channels. This scheme relies on choosing the best two antenna from all four possible antenna. Then a MIMO channel estimate method is proposed, which is based on AS-TR-STBC. This estimate is a novel method combining antenna selection and time-reversal STBC for multipath fading channels .Simulation show the proposed scheme outperforms all other schemes if the power for the useful antenna is reasonably considered.
