The paper discusses the part of asic design of tcm ( trellis coded modulation ) in hdtv 8vsb terrestrial channel broadcasting receiver chip. in testing, the tcm can improve the signal - to - noise by 3. 3db compared with uncoded 4 - vsb modulation, and with the 12 path intrasegment interleaving in tcm coding and viterbi decoding, system can control short burst noise error efficiently
在高清晰度電視通道接收晶元中內碼是8 ? vsb的格狀編碼,在系統性能上使用tcm編碼要比未編碼有3 . 3db的編碼增益,另外在格狀編碼中加入了12路的內交織,可有效的抑制短的突發噪聲對接收端viterbi解碼性能的影響。 -
