摘要

本文研究了仅在接收端可获得部分信道状态信息的超宽带(UWB)多输入多输出(MIMO)协同中继系统的误码率(BER)分析。在分析中,考虑了去耦转发(DCF)和解码转发(DF)中继方案。针对这些方案,通过数值结果研究了协同中继优于直接传输的中继区域以及功率优化的效果。

UWB MIMO cooperative relay systems: BER analysis and relay regions
In this paper, bit error rate (BER) analysis is presented for ultra-wideband (UWB) multiple-input multiple-output (MIMO) cooperative relay systems, where partial channel state information (CSI) is only available at the receiver side. In the analysis, decouple-and-forward (DCF) and decode-and-forward (DF) relaying schemes are considered. For these schemes, the relay regions, in which cooperative relaying outperforms direct transmission, and the effects of power optimization are studied through numerical results.
