ABSTRACT:
A cross polarization interference canceler includes a digital conversion circuit for subjecting a demodulated signal of one channel to an analog-to-digital conversion out of two channels which are independently formed using carriers having the same frequency but having planes of polarization which are mutually orthogonal. An interference cancelling circuit cancels interference caused by the other channel out of the two channels, with respect to the demodulated signal which is digitally converted by the digital conversion circuit. An integrator circuit performs an integration process with respect to the demodulated signal which is digitally converted by the digital conversion circuit so as to provide negative feedback to the digital conversion circuit.
