This paper proposes an optimal beam-selection DTV receiver which uses switched beam-selection techniques. Usually the ATSC DTV receiver uses equalizer for compensating channel distortion. But multipath signals and Doppler effect easily affected performance of the receiver in mobile and indoor environment. A proposed optimal beam-selection DTV receiver reduces multipath signals so a burden of equalizer is reduced, so channel compensation is easier than a conventional DTV receiver which uses only equalizer. Simulation results show that performance of the proposed system is better than a conventional DTV receiver
