中文摘要：

提出了一种基于有限新息率采样的频域多通道结构的TR-UWB数字接收机。传统频域接收机的通道数多、系统结构复杂，不满足UWB接收系统低功耗、低成本的要求。有限新息率采样技术不但突破信号带宽的限制，降低了UWB系统的采样率，同时对接收到的多径分量可进行压缩，简化了系统设计，使得TR接收机的数字化更易实现。仿真结果表明，频域多通道采样的TR数字接收机在误码率要求不高的情况下，降低了采样率。

英文摘要：

TR-UWB digital receiver based on finite rate of innovation sampling and frequency-domain muti-channel is proposed. The number of channels in traditional frequency-domain receiver is big, and its system architecture is complex, so it does not meet the UWB receiver＇s requirements of low power and low cost. Finite rate of innovation sampling not only breaks the limitation of signal bandwidth and reduces the sampling rate of UWB system, but also can compress the received multipath components and simplify the system design, so that it is easier to implement the UWB digital receiving system Simulation results show, fre queney-domain multi-channel digital receiver reduces the sampling rate when the demand of bit error rate is not high.
