ABSTRACT:
A symbol timing recovery method for DMT-VDSL is provided. The method converts the extracted sample to the frequency domain. Using the peaks and the company peaks in the frequency domain, the method determines the correct position of a peak response, thereby calibrating the sample extraction position. Thus, the symbol timing can be recovered.
