一种低采样率的UWB信号接收技术

UWB Receiver Technology of a Low Sampling Rate

针对目前UWB信号接收机对高采样率A/D器件的依赖给出了一种低采样率的UWB信号接收机结构。简要分析了该接收机的接收原理,以及加性白高斯信道中的接收性能,并以4路并行滤波为例,对该接收机的接收性能进行了计算机仿真。计算机仿真的误比特率结果表明,仿真结果与分析结果相近。

Due to the dependence of UWB signal receiver on A/D apparatus of high sampling rate at present, a structure of a low sampling rate receiver for UWB signals is proposed. The principle and the performance of the receiver in AWGN channel have also been analyzed. In the end we take four parallel filters as example and get the approximate results between the computer simulation and the theory analysis.
