Abstract :
System performance for a two branch maximum ratio combining (MRC-2) reception, with π/4DQPSK modulation and coherent differential detection, has been analyzed over multipath Rayleigh fading and co-channel interference (CCOI) channel. We show that computer simulation has substantially resolved the complication of theoretical analysis for this task. The average bit error rate (BER) performance are intensively investigated with various filtering roll-off factor, carrier-to-interference power ratio (C/I), and signal-to-noise power ratio (S/N). The fading rate is normalized as fdT=0.001
