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 wave interference from the second polarized wave. CONSTITUTION:The base band signals transmitted respectively with the horizontal and vertical polarized waves are fed to the input terminals 600, 601. The filter 4000 rejects the sum of the wave distortion of the horizontal polarized wave itself and the self interference and the sum of the cross polarized waves from the vertical polarized wave to output the horizontal polarized wave component only rejecting all the interferences at the output terminal 402. Similarly, the filter 4000' rejects the interference from the horizontal polarization and only the vertical polarized wave component is outputted at the output terminal 402'.
