Abstract
A cell search method in a multiple carrier wireless network includes a step of trying to select, among a list of candidate couples [carrier frequency; bandwidth], at least one candidate associated with at least one cell of the multiple carrier wireless network. The cell search method includes: a step of obtaining and ordering an initial list of possible candidate couples [carrier frequency; bandwidth] according to the multiple carrier wireless network; a step of reducing the initial list, delivering a reduced list, the reduced list including only candidates compatible with a predetermined communication mode of the multiple carrier wireless network, through a differential cross correlation of the candidate couples [carrier frequency; bandwidth] of the initial list; a cell search step in which a cross-correlation is performed by testing all time/frequency hypothesis for at least one candidate of the reduced list of candidates, delivering synchronisation information.
