Very-Sharp Filter Enhanced Compensation in ATSC 1.0 & ATSC 3.0

Tue. April 25| 3:00 PM - 3:30 PM | N256

We are on the cusp of substantial change in the US broadcast market. FCC repack will result in substantially reduced spectrum for over-the-air broadcast television. Digital adjacent channel cases will become more of a requirement. The linear pre-correction implemented within the DTV exciter must be capable of pre-correcting "Very-Sharp Tuned" filters to achieve the best RF shoulder and MER figures. RF filters should be designed for both ATSC 1.0 and ATSC 3.0 transmission The purpose of this paper is to present the requirements of adjacent channel filtering/combining in both ATSC 1.0 and ATSC 3.0 that will affect many DTV transmitters after the FCC repack. We will present the latest state-of-the-art RF Mask filter designed by Dielectric. Then, new Digital Linear Pre-correction techniques, especially designed by TeamCast to compensate such "Very-Sharp Tuned" filters will be explained. Finally, a comprehensive report and test results performed by Comark, TeamCast and Dielectric will conclude this presentation.
