In high speed mobile communication environment, time dispersion caused by multipath interference and frequency dispersion caused by Doppler shift weaken the effect of traditional frequency domain resource allocation algorithms on WFRFT-based hybrid-carrier systems. In order to solve this problem, this paper proposes a fractional domain resource allocation algorithm which is able to take the channel conditions into consideration. By adjusting the fractional order, the proposed method can suit different transmitted signals, therefore has better performance in time-frequency doubly dispersive channels. Simulation results show that the proposed fractional domain resource allocation algorithm has better BER performance than traditional frequency domain one in the hybrid-carrier system.
