提出一种数字电视接收机中消除模拟同频干扰的解决方案。经过实验室测试和现场路测证明,该设计结构与均衡器结合,在采用16QAM时,可降低9dB的同频干扰,采用4QAM时,可降低14dB的同频干扰。
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.
