Abstract :
A simple and efficient synchronization algorithm for OFDM based on training cyclic prefix is presented. First, the OFDM symbols are studied. And then a new OFDM synchronization algorithm using training cyclic prefix is presented. At last, the experiments of simulation are discussed. The simulation results show that the new algorithm not only improved the performance of symbol timing and fractional frequency offset estimation, but also estimated the integer frequency offset under certainty range. It can solve the synchronization problem of OFDM system in practice.
