Research on timing synchronization algorithm for OFDM systems in Rician channel

Abstract

OFDM is widely used in wireless communication with the development of the communication technology. Timing synchronization is the important part of the receiver in OFDM system. The performance of timing synchronization may have a great influence on signal reception. So far, many researchers have made a lot of studies on timing synchronization. However, classical algorithms always focus on AWGN channel and Rayleigh channel. However, the synchronization performance of classical ones will sharply decrease in Rician channel. This paper proposes a new timing synchronization algorithm based on Rician channel. Simulation results show that the performance is much better than the classical ones.
