A high precise method for symbol timing synchronization
Jin Li-jun · Journal of Xidian University · 2005
This paper presents a high precise method for symbol timing synchronization,which is realized by using a synchronization searching/tracking loop combined with the re-sampling of the input digital signal based on a multi-phase filter-bank whose filters are deduced from a low-pass filter prototype with different group delays.The method is a fully-digitized process at the sampling clock rate,so that it can be conveniently implemented by FPGA or DSP,whose synchronization precision can reach 1% of the sampling interval.
