Abstract :
The 64DAPSK-OFDM transmission techniques for DRM systems are investigated in this paper. The error probability of 64-DAPSK in mobile fading channel is evaluated and the optimum ring ratio and detection thresholds have been determined. Extensive computer simulation results show that 64DAPSK-OFDM is superior to the widely adopted 64QAM and it can he a potential choice for spectrally efficient digital transmission over different DRM channels.
