    摘要： An orthogonal cross-polarization interference compensating device for solving the problem tin which integration contents of an integration circuit are indefinite when a control loop is cut. An orthogonal cross-polarization interference compensator generates a compensation signal for compensating phase noise included in an own polarization signal. A demodulator compensates for orthogonal cross-polarization interference based on the compensation signal for the phase noise included in the own polarization signal. An error detector generates an error signal indicating phase difference between the own polarization signal compensated by the demodulator and a proper own polarization signal. A phase noise phase detector generates a differential signal indicating phase difference between the own polarization signal and other polarization signals based on the compensation signal and the error signal. An integration circuit integrates the differential signal and generates an integration signal. An infinite phase-shifter adjusts the compensation signal based on the integration signal. A control circuit determines whether or not orthogonal cross-polarization interference is present based on the compensation signal adjusted by the infinite phase-shifter, and adjusts the integration value indicated by the integration signal to be a predetermined value when there is no orthogonal cross-polarization interference.

    摘要： At a transmitting side, during carrier leak adjustment, quadrature modulation means uses a carrier wave having a frequency different from that at a receiving side to quadrature-modulate an outgoing signal. Feedback means feeds a modulated wave resulting from the quadrature modulation back to the receiving side. At the receiving side, quadrature demodulation means quadrature-demodulates the fed back modulated wave. Phase locking means locks the phase of the signal resulting from the quadrature demodulation to match the phase to the phase at the transmitting side. Offset detection means time-averages the phase-locked signal to detect a direct-current offset. At the transmitting side, based on the value of the direct-current offset detected at the receiving side, offset adjustment means corrects a direct-current offset of the outgoing signal to be quadrature-modulated.
