An Efficient Joint Algorithm of Synchronization, Channel Estimation and the Low Peak-to-Average Power Ratio for OFDM System

Based on the key technology of high data rate wireless communication systems-Orthogonal Frequency Division Multiplexing(OFDM), an efficient joint algorithm is proposed. This method can realize synchronization, channel estimation and the low peak-to-average power ratio of OFDM system. To do this, the OFDM system exploits a training sequence to achieve synchronization and channel estimation, and to lower the peak-to-average power ratio with the coefficients of partial transfer sequece (PTS) algorithm. Results of simulations indicate that the OFDM system with the joint algorithm can simultaneously realize synchronization, channel estimation and the low peak-to-average power ratio and be implemented with reduced complexity and improved validity by using one training sequence.
