  Abstract

In this paper, we proposed an efficient scheme that estimates and compensates the Doppler frequency occurring in the mmWave based high-speed railway OFDM communication systems. A combination scheme of an uplink M-UCCH signal and a new M-USCH channel showed better performances than the previous M-USCH structure in the pilot-correlation based frequency offset estimation algorithm. Also, the 1-stage scheme employing the M-UCCH signal can reduce the hardware complexity of the frequency offset compensation and improve the transmission performance by assisting the M-USCH channel to be well-designed.
