Research on the Robust Modulation for the reception improvement of VSB System in dynamic multipath channel

동적다중경로 채널에서 VSB시스템의 수신성능개선을 위한 강인한 변조기법 연구

This paper presents a new baseband modulation system for the reception improvement of VSB system in dynamic multipath channel. By introducing the 1/2 Trellis Coded Modulation in baseband modulation, the TOV of proposed modulation is improved very much compared with 8-VSB modulation and better than the pseudo 2-VSB modulation of Philips which is the most robust modulation for VSB transmission system as far. Through the computer simulation, the performance of the proposed modulation is examined and the results are shown.
