  • System for the automatic correction of polarization distortion in multichannel radiocommunication station
    Patent number: 3986123
    Abstract: A station for the transmission and reception of electromagnetic waves (e.g. from a communication satellite in stationary earth orbit), operating in a multichannel band with two conjugate polarizations, includes a regenerative distortion compensator in a receiving waveguide branch and a predistorter in a transmitting waveguide branch, both controlled by a processor responsive to output signals from a subsequent i-f stage in which a distortion monitor measures cross-talk between the two polarizations on the basis of two central beacons extracted from the incoming message band.
