Analysis of Channel Equalization Techniques of ATSC Main and Mobile Transmission System
After introducing digital HDTVs, smart consumers now require new DTV services. ATSC (Advanced Television System Committee) 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.
