Abstract
The present invention concerns a signal processor module (SPU,AVF) which is adapted to check if a received vector (RV) representing a received signal in a QAM signal vector plane is located in the intersection zone of a first and second zone (ABCDEF,ab) of this signal vector plane. The intersection zone is well chosen so that the phase angle difference (Da) between the received vector (RV) and an expected vector (EV) which represents a signal which should have been received instead of the received signal and which is located in the intersection zone, is limited.
