In this paper, we proposed a novel SK-OFDM scheme which has a good tolerance of deep fading channels, such as vehicular communication channels. By introducing the idea of spectral keying into OFDM scheme, the system has a better chance to recover the sub carriers with deep fading. We investigate the performance of proposed scheme over channel with spectral nulls and show how SK-OFDM gets advantage comparing to the conventional OFDM. The result of system simulation is in accordance with theoretical analysis.
