摘要:

针对超宽带（UWB）通信中数据辅助平均发射参考(ATR)接收机在判决错误较多时性能恶化的问题，提出了在相关器后串联Turbo乘积码（TPC）的译码器，取其译码判决输出来反馈更新相关模板，以降低判决错误数量的解决方案，据此形成了一种改进的应用TPC码的判决反馈ATR接收机。理论分析和IEEE CM3多径信道仿真结果表明：该接收机的检测性能优于一般ATR+TP C码纠错的接收机，在10-4误码率时约有1 dB的信噪比增益优势。

Abstract:

The performance of a data-aided ATR(Average Transmitted-reference) receiver in Ultra-Wideband(UWB) communication will worsen when the decision errors are muc h more. A solution is proposed to reduce the number of detection errors by addin g a Turbo product code (TPC) decoder after the correlator and using the feedback from the decision output of the decoder to update the correlation template. Acc ordingly, an improved decision feedback ATR receiver using TPC is presented. The oretical analysis and simulation in IEEE CM3 multipath channel show that it has better detection performance compared with the conventional ATR+TPC code receiv er, and has about 1 dB Eb/N0 gain at 10-4 bit-error-rate(BER).
