高速超宽带脉冲检测电路的设计

Design and realization of RF detect circuits in high speed UWB receiver

在介绍了一种基于TH-PPM调制方式的并行检测接收机方案的基础上,结合UWB脉冲信号的时域特征提出并实现了一种结构简单、性能稳定的脉冲能量检测电路。实验结果表明该电路可在100Mb/s的高传输速率情况下取得较好的超宽带信号检测效果。

The key technique in Ultra-wideband （UWB） communication system, namely technique of UWB pulse signal detection and receiving. This paper advances a parallel detection receiver scheme, and gives an easy to Realization and structure-simple energy detector by combining the time domain character of UWB pulse signal. The experiment has proved that the circuits can get well performance in the case of high communication rate if combining the FPGA.
