摘要

脉冲无线电(IR)是一种超宽带(UWB)跳时扩频技术，它通过改变脉冲在时间轴上的位置来调制亚纳秒脉冲来传递信息。研究了天线阵列接收机在多径环境下多用户干扰下的UWB系统信道估计问题。该估计方法是基于极大似然准则的导频符号辅助估计方法。

A pilot symbol assisted channel estimation scheme for UWB IR systems with diversity reception

Impulse radio (IR) is an ultra-wideband (UWB) time-hopping spread spectrum technique in which sub-nanosecond pulses are modulated to convey information by shifting the position of the pulses in the time axis. We investigate channel estimation for an IR UWB system with an antenna array receiver in multipath environments with multiuser interference. The estimation method is pilot symbol assisted and it is based on the maximum likelihood criterion.
