We propose a reception improvement method for ATSC (Advanced Television Systems Committee) 8 VSB in severe multipath channel using directional diversity. The VSB system has only about 0.3% of known training signal for the receiver in a data field and the reception performance of VSB receiver is degraded significantly when there are near-0 dB ghosts in received signal. To overcome this problem, the directional diversity is suggested. By applying directional diversity, we can eliminate undesired multipaths, so improve 8 VSB reception performance. We demonstrate the performance of proposed method under severe multipath channel and show it can improve the reception of 8 VSB system.
