- Abstract
- We propose a reception improvement method for ATSC(advanced television systems committee) 8VSB 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 8VSB reception performance. We demonstrate the performance of proposed method under severe multipath channel and show it can improve the reception of 8VSB system. © 2007 IEEE.
