Abstract :
A new sampling clock synchronization method using improved early-late gate and least-square fitting in OFDM system is proposed in this paper. Improved early-late gate is used to obtain symbol timing offset and least-square fitting works like a loop filter in the feedback branch which can be achieved by recursion. Recursion process is then amended to overcoming some shortcomings. Theoretical analysis and computer simulation demonstrate this method have a good performance.
