- Abstract
- This paper proposes an enhanced 8-VSB DTV receiver using spatial diversity technique, which is consisted of two beamformers and a simple equalizer. Beamforming technique is very helpful to improve performance of a conventional DTV receiver. But DTV receivers combining beamforming technique have limitation of hardware implementation according to the number of antenna elements. So sometimes performance degradation occurred by insufficient degree of freedom. Diversity technique can solve that problem by combining adaptive beamforming technique. Proposed DTV receivers have fast convergence speed and an input SNR gain according to the number of antenna elements and beamformers.
