摘要

针对多天线冲激无线电超宽带通信系统

提出了一种盲的线性接收机。在不需要信道信息的情况下

可以利用经过预编码的空时分组码给接收信号带来的特定结构

直接得到接收机系数

从而恢复出发送符号。仿真表明

随着用于估计的数据块的增加

盲接收机的性能逐渐接近于相关接收。

Abstract

A blind linear receiver for multi-antenna impulse radio ultra-wideband（UWB）communication systems was proposed.Without the need of channel information

specific properties of the received data imposed by the precoded space-time block codes（STBC）could be exploited to estimate the coefficients of the receiver

which subsequently recovered the transmitted symbols.Simulations show that

with the increasing of the data block for estimation

the performance of the blind receiver approaches that of the coherent one.
