- In August 2014, ATSC adapted 3DTV standard which is service compatible 3DTV using main and mobile hybrid delivery (SC-MMH), and the 3DTV standard uses the ATSC M/H transmission system. Because the M/H system transmits both main and mobile training sequences for equalization, ATSC 3DTV reception performance can be improved by using both training sequences. This paper introduces the LMS-DFE and proposes an equalizer concatenated with channel estimation. And the computer simulations were performed on Rician channel of K = 0 dB and Rayleigh channel in order to evaluate the performance of both equalizers. Simulation result shows that the proposed equalizer works well on both channels within the time of a half VSB frame.
