<p>PROBLEM TO BE SOLVED: To provide a cross polarization interference removing device capable of pull-in setting with the maximum capability of the device all the time because pull-in setting for the cross polarization interference removing device on the present polarization side could not be performed until a cross polarization interference quantity is improved to a level below a pull-in setting/out-of-synchronism point at the time of cross polarization interference remover stop when the cross polarization interference quantity gradually decreases from the state of out-of-synchronism conventionally caused by the great cross polarization interference quantity. SOLUTION: This device is provided with a mask control circuit 6 for performing control to mask a cross reset signal, which is outputted when a different polarization side device 102 is abnormal, in the abnormal state of a present polarization side device 101. Thus, when the cross polarization interference quantity gradually decreases from the state of out-of- synchronism caused by the great cross polarization interference quantity, even when the cross reset signal from the different polarization side device is outputted in the abnormal state of the different polarization side device, pull-in setting is enabled at the moment when the cross polarization interference quantity becomes lower than the pull-in setting point at the time of cross polarization interference remover operation, and pull-in setting is enabled at any time with the maximum capability of the cross polarization interference removing device.</p> |
