Abstract

PURPOSE:To perform the cross polarized wave compensation system at the base band based on the demodulation base band signal information, by providing the filter obtaining the first series superimposed on the first polarized wave through the rejection of the cross polarized interference from the second polarized wave. CONSTITUTION:The polarized wave 1 desired is inputted to the synchronous detector 72 and the polarized wave 2 causing polarized wave interference is inputted to the synchronous detector 73. The carrier of the polarized wave 1 is extracted at the carrier extracting unit 77 and fed commonly to the shnchronous detectors 72, 73. The output of the synchronous detectors 72, 73 is inputted to the input terminals 400, 401 of the filter 4000 to reject the sum of the wave distortion of the polarized wave 1 itself and the self interference, and next, the sum of the cross polarized wave interferences is rejected to obtain the output of the component of the polarized wave 1 only rejecting all the interferences at the output terminal 402.
