Enhanced-xVSB system development for mobile/portable reception

The paper describes an enhanced-xVSB system for improving mobile/pedestrian reception performance to the ATSC DTV 8-VSB transmission standard. The proposed system is fully backward compatible with the current ATSC 8-VSB standard. For mobile and portable reception support, the E-xVSB system adopts a reduced constellation method as well as an enhanced trellis-coded modulation scheme.
