Description
A Time Spread Modulation-differential QPSK (TSM-DQPSK) with differential detection system is proposed to improve bit error rate performance in Rayleigh Fading channels. TS symbols are mapped to phase difference of DQPSK. BER performance of proposed system in Rayleigh fading channels is investigated by computer simulation. It is shown that the process gain of the proposed system is about 2.5dB at BER=10^<-2> and 7dB at BER=10^<-3>, compared with BER performance of uncoded DBPSK.
