Abstract :
This paper proposed a SK-OFDM scheme to combat frequency selective fading in vehicular communications. By introducing the idea of spectral keying into conventional OFDM used in IEEE 802.11p standard, the system performs better in recovering subcarriers with deep fading. Simulations show the 2-order SK-OFDM outperforms traditional OFDM about 2 dB when ber = 10-3 and SK-OFDM is able to remove the BER floor occurred in conventional OFDM.
