Abstract :
In this paper the performance of non-coherent differential amplitude phase shift keying (DAPSK) modulation over fast frequency nonselective and frequency selective fading channels are evaluated, respectively, through comprehensive simulations. The existence of hounds on DI6APSK and D64APSK for fast Rayleigh fading channel is verified. Based on the bound, a Doppler spread restriction on DAPSK operation in very high mobility environment, such as the high-speed railway communications, is found. Moreover, the ISI impact on high Doppler multi-path environment for DAPSK is investigated and analyzed.
