Patent ID: 8890728

Claim:
A method for processing a sampled signal which comprises M original trains of original samples respectively arising from M temporally interleaved converters, M being greater than two, the method comprising a first processing which comprises: selecting an original train in as a reference train; for the M−1 other original trains, performing at least one estimation of a suite of M−1 shift coefficients that represent clock shifts between the M−1 other original trains and the reference train; wherein the at least one estimation comprises a correlation processing involving at least one part of the sampled signal, at least one part of at least one first signal gleaned from a derived signal representative of a temporal derivative of the sampled signal and at least one part of N partial filtered signals respectively representative of N weighted differences between N pairs of bracketing versions flanking the sampled signal, N being greater than or equal to 1, the at least one estimation also comprising a matrix processing on results of this correlation processing.
