In this paper, we propose the use of constellation rotated vector OFDM (CRV-OFDM) to combat a fast fading channel, which accompanies with carrier frequency offset (CFO) and Doppler frequency spread (DFS). Employing Gaussian approximation of interference, we give pair-wise error probability bounds of CRV-OFDM in terms of the CFO and DFS. The theoretical analysis indicates that robustness of CRV-OFDM against fast fading increases with M, the length of vectorized symbols, and such argument is confirmed by running computer simulations.
