Abstract To remove the impacts of polarization interference on satellite-to-ground high-speed data transmission systems, the major factors that affect polarization interference are concluded, the deteriorations of bit error rate (BER) of different modulation systems and channel coding modes are simulated, and the parallel adaptive filtering technology is presented to resolve the high symbol-rate signal transmission polarization interference. It has been verified by experiments that the effects of this method is remarkable. In the situation of QPSK system, 500MSPS symbol rate and 10 dB polarization isolation, the BER performance can be improved 4.5 dB by using this method.
