分析了全数字高清晰度电视（HDTV）中地面广播信道的干扰及抑制措施，给出了抑制同频干扰的梳状滤波器的设计方法和HDTV中8-VSB基本原理及传输方案，并基于传信率1／T＝23．548Mbps的8—VSB作了计算机模拟。
The interference and suppression measures of terrestrial broadcast channels in all-digital high-definition television (HDTV) are analyzed. The design method of comb filter to suppress co-channel interference and the basic principle and transmission scheme of 8-VSB in HDTV are given. 8-VSB with a transmission rate of 1 / T = 23.548 Mbps was simulated by computer.
