Performance of TR-UWB Digital Receiver Based on A/D Conversion and Its Implementation on FPGA
摘要
Abstract
TR-UWB system uses an autocorrelation detection as a suboptimal receiver,it is no need to do channel estimation and exact time synchronization.The implementation is simple and its performance is good.Digitalized TR autocorrelation receiver can use the current digital signal processing technology to be realized by the integrated circuit easily.During the implementation,ADC performance is one of the key factors to be considerer.This paper analyzes the effects of the sampling rate and the quantitative order to the digital receiver theoretically.And it is proposed that high quantization order cannot improve the system function.Finally,a TR-UWB digital receiver is implemented based on FPGA.By programming design and simulation,it is concluded that TR-UWB digital receiver based on ADC can be achieved.关键词
