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

Abstract

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.
