A device and a method for deviation determination for use during transfer of a phase shift modulated information-carrying signal between a transmitter and a receiver. The deviation determination is based on the presence of phase-linear segments, i.e., parts of sequences of phase changes that have the...http://www.google.fr/patents/US6091789?utm_source=gb-gplus-shareBrevet US6091789 - Method and device for phase modulated signals
