METHOD AND DEVICE FOR RECEIVING A SIGNAL THE PHASE OR FREQUENCY OF WHICH IS MODULATED BY A SEQUENCE OF TWO-STATE SYMBOLS

摘要

The present invention relates to a method (50) allowing a receiver device (31) of a wireless communication system (10) to receive a useful signal emitted by an emitter device (20), said 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, including: detecting (51) a temporal envelope of the useful signal; comparing (52) the detected temporal envelope to a preset threshold value (S1); detecting (53) transitions between consecutive useful-signal symbols, on the basis of the result of the comparison; and, extracting (54) the sequence of binary data from the useful signal depending on the detected transitions.
