ABSTRACT:
In order to reset a cross-polarization interference canceller for use in a digital radio communications receiver, two polarized-signal discriminators are provided in a manner to be coupled respectively to receive reproduced digital data from the corresponding demodulators. In the event that the demodulator produces an output not characteristic thereof, the corresponding polarized-signal discriminator produces a reset signal to reset the canceller.
