After introducing digital HDTVs, smart consumers now require new DTV services. ATSC has adapted 3DTV standard which is ATSC SC-MMH (Service Compatible 3DTV using Main and Mobile Hybrid delivery), and the 3DTV standard uses the ATSC M/H transmission system. Even though an 8-VSB frame has only 0.8% training sequence, an ATSC M/H frame has about 3.9% training sequence when the number of group is 8. So the longer training sequence of ATSC M/H can be used to improve the performance of channel equalization technique. This paper uses LMS-based channel equalization techniques, and compares the equalization performance of ATSC M/H transmission system with ATSC 8-VSB system. By the benefit of longer training sequence of ATSC M/H, the equalizer works well in Ricean channel of K = 0 dB.
