Use of the space-frequency block coded orthogonal frequency division multiplexing (SFBC-OFDM) is advantageous in high-mobility broadband wireless system but it is sensitive to the intercarrier interference (ICI) caused by phase noise (PHN). In this letter, the effect of PHN for Alamouti SFBC-OFDM system is analyzed and correlative coding (CC) is used to reduce ICI. Based on the expression of the ICI power for the Almouti SFBC-OFDM system with CC, the optimal CC coefficients that minimize the ICI power are obtained. Numerical results show that optimum CC can effectively increase the carrier-to-interference ratio (CIR) and improve the bit error rate (BER) performance.
