TPC译码反馈在超宽带TR接收机中的应用
Application of TPC decoding feedback for ultra-wideband TR receiver.
摘要
Abstract
In Ultra-Wideband(UWB) communications, the detection performance of a Data-Aided(DA) Averaged Transmitted-Reference(ATR) receiver becomes worse when the decision errors are spread. Aimed at this issue,an idea is proposed by adding an FEC decoding feedback mechanism and using the feedback from the decision output of the decoder to update the correlation template.By comparison, Turbo Product Code(TPC) is selected as the most suitable code.Thereby an improved DA-ATR receiver using TPC decoding feedback is presented. This receiver is analyzed and simulated in multipath channel. The results show that it can effectively eliminate the above risk, and it has about 1 dB Eb/N0 performance gain superiority compared with a conventional TPC encoded ATR receiver.关键词
