1. A method for detecting a signal in a communication system including a plurality of communication channels, from a plurality of noisy values respectively representative of the transmission through said communication channels, propagation in said communication channels being characterized by at least one variable, a set of values able to be taken by said at least one variable being divided into a plurality of ranges, said method comprising:
receiving signals respectively transmitted in the plurality of communication channels; and
detecting a signal corresponding to a value of said at least one variable included in one range among the plurality of ranges by comparing, with a predetermined threshold, a value taken by a correlator linked to the one range and calculated as a function of the noisy values, the detecting the signal comprising determining, for each of the ranges, a sum of windowed correlator functions associated with the respective range and depending upon said noisy values.
