Abstract:
1. An apparatus for receiving a signal of digital broadcasting service, comprising: an array antenna having a plurality of antenna elements, each antenna element for receiving signals from the digital broadcasting service; a demodulation means for demodulating the broadcast signals, each corresponding to each of antenna elements included in the array antenna; beam-forming means for receiving demodulated signals of the demodulation means to generate a predetermined number of beamformed signals based on different beam-forming weights in order to steer each of the predetermined number of beamformed signals to a predetermined direction according to the demodulated signals; and beam selection means for selecting one of the predetermined number of beamformed signals based on each predetermined direction of the predetermined number of beamformed signals, wherein the selected beamformed signal has the most desirable direction, wherein the demodulation means includes a plurality of demodulators, the number of demodulators equaling the number of antenna elements in the array antenna.
