Abstract
A method is provided for channel scanning in a wireless communications system, for the identification of one or more narrow-band channels present in a certain frequency band and which can be used for connection between a wireless communications device and a communications network. The method includes: applying a FFT function to at least one signal corresponding to a given frequency band, providing for a set of coefficients each being representative of a frequency, analyzing the coefficients so as to detect at least one frequency region having at least one predetermined feature, and determining at least one channel position, by considering that each of the at least one frequency region having at least one predetermined feature is a guard band of one of the at least one channel.
