"Researcher of cellular telephony, and.Process for each of the at least one mobile station to identify at least one channel and multi - path to use to communicate with one of the at least one base station in a telephone network cel(reset ". A searcher (10) for a mobile station of a cellular telephony network.The pilot signals of base stations nearby are correlatados with a succession of pseudo noise within a search window, using a bank of correlatores (20).Each correlator (20) is assigned to a different delay, among a series of delays in the window (14). In each delay, correlation is performed initially for a first time of residence.If the value of the resulting correlation exceeds a threshold, the correlation is continued to a second residence time. Otherwise, the correlator (20) is adjusted to the next delay in succession.Only the outputs of second correlations of residence are used to identify the base station closest to it.Some correlations may execute the first correlations of residence in new delays in the same time than other correlatores are still running second correlations of residence in delays antA major player in the window.
