摘要: Abstract: OFDM system divides a wideband transmission bandwidth into several overlapped narrowband subcarriers to avoid the serious frequency selective fading problem. However, if Timing Offset (TO) and Carrier Frequency Offset (CFO) exist between the Transmitter (Tx) and Receiver (Rx), OFDM system will suffer the Inter-Symbol Interference (ISI) and Inter-Carrier Interference (ICI) that degrade the system performance dramatically. In this paper, we propose a simple modification of the S&C method. We adopt the overlap concept to reduce the plateau problem. Simulation results show that with this simple modification, it can improve the timing synchronization performance of the S&C method greatly.
