| Abstract: | This paper analyses the effects of trellis coded modulation(TCM) and adaptive technology on HDTV transmission system or interference circuments of HDTV simulcasting transmission. We give steps of combating interferences. We design a concatenated coding scheme, consisting of a trellis code and a Reed-Sdomon code, which is suitable for HDTV application. The simulation results for this scheme indicates that it has a good error performance. |
