研究了一种一般的平均传输参考接收机的结构，并推导了该结构下的误码性能。该结构充分利用了超宽带信道准静态的特点，将一个接收比特的参考脉冲累加求平均作为模板信号，从而降低加性噪声的影响。在IEEE802．15．3a标准下0-4m非直射路径的信道下，采用Scholt＇z单循环脉冲和二进制相移键控调制，分别在不同脉冲重复数和不同积分时间情况下，对平均传输参考接收机进行性能仿真与对比。另外，还将该接收机与一般的传输参考接收机和一种改善的传输参考接收机在接收性能方面进行了理论和仿真对比。

A general Average Transmitted Reference （ATR） receiver is researched, and the BER performance of the ATR structure is deduced in detail. Based on the character of Uhra-Wideband quasi-stationary channel, the received reference pulses in a single bit duration are summed up and averaged afterly as the template signals, which can reduce the effect of additive noise. The ATR performance results are evaluated for both the different pulse repetition numbers and the different integration integration time in BPSK single user by using IEEES02.15.3a 0-4 m NLOS channel model and the Schohz＇s monocycle waveform. In addition, the BER performance of ATR receiver is compared with both the basic transmitted reference receiver and the modified transmitted reference receiver.
