%X For Orthogonal Frequency-Division Multiplexing (OFDM) communication systems with high mobile speed, the frequency offset caused by Doppler frequency offset and the frequency differences will introduce Inter-Carriers Interference (ICI), which degrades the performance. Based on the analysis of the interference mechanism of ICI, a high efficient ICI cancellation scheme based on differential coding in terms of channel estimation is introduced. This scheme improves the spectrum usage efficiency of ICI self-cancellation. And compared with the normal OFDM system, the proposed scheme has 4dB channel estimation improvement and avoid the error floor caused by ICI.
