Abstract:

This paper utilizes the decided symbols and their corresponding received signals to devise a reference signal for demodulation, and presents a structure of UWB autocorrelation receiver based on the decision feedback average (DFA). Theoretical performance of DFA autocorrelation receiver is analyzed in a resolvable multipath channel. Its upper bound is given for low bit error rate (BER). Simulation results verify that the performance of DFA autocorrelation receiver is superior to autocorrelation receivers with conventional transmitted reference, differential transmitted reference, and average transmitted reference. The DFA autocorrelation receiver can be improved by increasing the number of feedback symbols.

Key words: autocorrelation receiver, decision feedback average (DFA), conventional transmitted reference (CTR),
average transmitted reference (ATR), differential transmitted reference (DTR)
