초록
A receiver for improving reception ability of digital broadcasting service by switched beam-forming is disclosed. The receiver includes: an array antenna having a plurality of antenna elements for receiving signals of the digital broadcasting service; a demodulation unit for demodulating the receiving signals corresponding to each of antenna elements in the array antenna; beam-forming unit for generating a predetermined number of beam-forming signal by applying a beam-forming weights in order to direct to a predetermined direction according to the modulated signal from the modulation unit; and beam selection unit for selectively receiving signals of desired direction according to the beam forming signal. The present invention effectively eliminates multipath based on space filtering by utilizing beam-forming method with an array antenna for improving receiving performance of digital television broadcasting with VSB.
