  • In Orthogonal Frequency-Division Multiplexing (OFDM) system, when using the partial power training sequence to synchronize, the received data signals will be seriously interfered by the training sequence. Due to the imperfect channel estimation, even if the training sequence separation technique is used, errors will also occur while using the inadequate knowledge of channel to perform the training sequence separation. This paper proposes an optimum method to suppress the interference from the training sequence to the data bearing OFDM symbols in frequency selective fading channels. A closed form formula for the optimized training sequence canceling factor is given by the theoretical analysis and its reasonability is verified by the simulation results.
