Abstract
A method allowing a receiver device of a wireless communication system to receive a useful signal emitted by an emitter device. The useful signal corresponding to a signal, the phase or frequency of which is modulated by a sequence of two-state symbols corresponding to a sequence of binary data. A temporal envelope of the useful signal is detected and compared to a preset threshold value. Transitions between consecutive useful-signal symbols are detected, on the basis of the result of the comparison. A sequence of binary data is extracted from the useful signal depending on the detected transitions.
