ABSTRACT:
A method for determining symbol boundaries in an ADSL modem, comprising receiving multi-frequency modulated signals in the time domain, wherein the multi-frequency modulated signals include a pilot signal at a pilot frequency. Performing a time-to-frequency transform on the multi-frequency modulated signals to recover the pilot signal. Iteratively computing a phase error for the pilot signal over a number of transform regions. Selecting the transform region with the lowest phase error.
