Abstract: PURPOSE: A digital broadcasting reception device improving receiving performance through a selective beamforming function is provided to apply a beamforming method using an array antenna for introducing a spatial signal processing system to an existing time signal processing system, and to remove dynamic multiple paths, thereby improving reception performance of a VSB(Vestigial Side Band) transmission system. CONSTITUTION: An array antenna(210) consists of many antenna elements, and receives digital broadcasting signals. A demodulator(220) demodulates each of the received signals by corresponding to the antenna elements of the array antenna(210). A beamforming unit(230) applies beamforming weight in order to steer for a predetermined direction relating to the modulated signals, and generates predetermined beamforming signals. A beam selector(240) selectively receives signals of a desired direction for the beamforming signals. The array antenna(210) is a linear array antenna having the antenna elements.
