摘　　要：提出了一种改进的超宽带(UWB)差分传输参考(DTR)接收机,通过在DTR接收机前加一个信道缩短均衡器,有效地减少等效信道长度,消除符号间干扰。在UWB信道模型中,对改进的DTR接收机的误码性能进行仿真,实验结果表明,在相同系统仿真参数条件下,改进的DTR接收机明显优于传统的DTR接收机。In this paper,an improved differential transmitted reference(DTR) receiver for Ultra-Wide Band(UWB) is proposed.Before DTR receiver,a channel shortening equalizer is added,which can effectively reduce the number of channel taps and alleviate the inter-symbol inference.Under the realistic UWB channel model,the improved DTR receiver is simulated in terms of bit error rate(BER).Simulation results show that,given the same parameters and constraints,the proposed receiver performs better than DTR receiver.
