Abstract	The paper proposes digital beamforming algorithms for vestigial sideband (VSB) based digital TV (DTV) receivers. We consider two types of beamforming algorithms, based on selection and adaptive beamforming algorithms. In the selection beamforming scheme, we make N fixed beams and select one. To do this, we compare the correlations of the received signal through each fixed beam with the pilot symbols. In the adaptive beamforming scheme, we use the least mean square algorithm to get beamforming weights. To be applicable to the VSB system, we modify the standard beamforming algorithms used in cellular communication systems. To apply these algorithms, we have developed a simple VSB system simulator including VSB modulator, synchronizers, and an equalizer. In the VSB modulator, we use the Hilbert transform and the raised-cosine filter. In the synchronizers, we implement the Gardner detector to recover timing synchronization. We use a decision-feedback equalizer. We demonstrate the performance of the proposed system under the Brazil channel model, and show that the beamforming algorithms can improve the overall system performance matching with other parts in the simulation.
