Abstract
A method, and related apparatus, for determining symbol alignment in a discrete multi-tone communications system comprising the steps of: receiving a signal on each of at least one selected carrier frequency; for each of a plurality of receiver window alignments with respect to said signals, deriving a measure of received signal power level on each said selected carrier frequency; for each said receiver window alignment and selected carrier frequency deriving a measure of spectral leakage on at least one adjacent carrier frequency; selecting a receiver window alignment responsive to said derived measures.
