Abstract:
1. A first communication device connectable to a corresponding second communication device through a local communication channel for carrying out cross-polar interference cancellation of a received radio signal, said first communication device comprising: a first QAM demodulator and a second QAM demodulator for demodulating a first one of two orthogonal components of the radio signal; a first analog differential interface stage and a second analog differential interface stage connected downstream of a respective one of said first and second QAM demodulators, for transmitting respective QAM demodulated components of said first component of the radio signal as differential analog signals over said local communication channel, and a digital data stream source for generating a digital data stream containing information to be shared with said second communication device and which information is fed to said first and second analog differential interface stages as a common mode signal for communicating said information in a digital channel embedded into the local communication channel.
