| Abstract: | A method to reduce co-channel interference in the digital television receiver is proposed. By lab-test and field-test, it is proved that, combined with equalizer, the proposed architecture can reduce 9 dB co-channel interference when using 16QAM and 14 dB co-channel interference when using 4QAM. |
