ABSTRACT:
The inventive receiver has a receiving branch for each of the two signals (EH, EV) and a demodulator (MHE, MVE) and means (SH, SV) for synchronising the phase of the received signal (EH, EV) with the transmitting phase are provided in said branches, respectively. Polaristion decouplers (XPIC-VH, XPIC-HV) which compensate cross-polar crosstalk between the two received signals (EH, EV) are provided for both of the receiving branches. The polarisation decoupling (XPIC-VH, XPIC-HV) of the two received signals (EH, EV) takes place after they have been demodulated (MHE, MVE) and before they have been phase-synchronised (SH, SV) so that the receiver can function as inexpensively as possible in terms of the components that it requires and so that it can also compensate cross polar channel crosstalk for circular QAM signal constellations.
