摘要

本文在IEEE 802.15.3a信道模型的CM1和CM3两种情况下，对一个包含决策反馈均衡器(DFE)的基带多输入单输出(MISO)时反转超宽带系统(TR-UWB)进行了评估。推导了基于高斯近似的半解析性能，并与仿真结果进行了比较。结果表明，该方法可以很好地近似分析误码率(BER)，并且DFE和发射天线数量的增加可以提高系统性能。

Improvement of MISO Single-User Time Reversal Ultra-Wideband Using a DFE Channel Equalizer

In this paper a baseband multiple-input single-output (MISO) time reversal ultra-wideband system (TR-UWB) incorporating a decision feedback equalizer (DFE) is evaluated over the scenarios CM1 and CM3 of the IEEE 802.15.3a channel model. A semi-analytical performance based on a Gaussian approximation is derived and compared with simulation results. The results show that such approach represents a good approximation for the bit error rate (BER) analysis, and that the DFE, as well as an increase in the number of transmit antennas, improve the system performance.
