ABSTRACT:
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 same phase change. Segments having three or more consecutive phase changes of the same value are extracted. An identification of the filtered-out segments is performed in order to determine which nominal phase-linear sequences the segments belong to. After this, the deviation and possibly a correction signal can be determined.
