| 摘 要： | 利用窄带滤波器设计技术,提出了一种新型UWB接收机设计方法,并定量给出了滤波器中心频率和带宽设计的要求。该方法能够以脉冲重复速率对接收到的信号进行采样,从而有效地降低了系统对A/D器件采样速率的要求及低噪放大器(LNA)的带宽需求,同时其性能也得到了一定的改善。计算机仿真结果表明了该设计方法的有效性。

| Abstract: | With a devising technique of the narrowband filter,a new design method of the UWB receiver was presented and the demand for design of the filter center frequency and bandwidth also were quantificational given.This method can provide a sampling for the received signals with impulse repetition rate,thus both the analogue-to-digital converter (ADC) apparatus sampling rate requested by the system and the bandwidth of the low noise amplifier (LNA) could be effectively reduced.Simultaneously their performance could be definitely improved.The validity of our idea could be indicated by the computer simulation results presented in the end of this paper. |
