Abstract：In modern complex communication environment, both the time interference and frequency interference cannot be ignored in the wireless communication channels. In the condition of high speed environment, large Doppler offset appears because of the relative motion between the transmitter and the receiver. Besides, as a result of being reverberation diffraction and scattering, signals may arrive at the receiver from some different paths. In this paper hybrid carrier (HC) system based on 4-WFRFT is designed which is proved to be having a better performance in time-frequency channels. In addition, partial FFT modulation beamforming algorithm is used to improve transmission efficiency, with a special pilot, the communication system can get a better performance even the length of the cyclic prefix is shorter than the time-delay. In this paper 2.7% are promoted with the algorithm proposed. When the time spreading is worse, the promotion can even reach 5%.
