OFDM RECEIVING DEVICE FOR BEAM FORMING WITH UNEVEN BEAM WIDTH BASED ON CHANNEL PROPERTIES AND COMMUNICATION UNIT AND METHOD EMPLOYING IT

摘要

PROBLEM TO BE SOLVED: To provide an OFDM receiving device for adjusting a beam formation azimuth through a plurality of antennas and to provide a communication unit and method employing it. SOLUTION: The OFDM receiving device with a plurality of antennas provided independently is characterized in that the device includes a receiving signal generating unit 100 for decoding and restoring OFDM signals from the antennas, a beam coefficient calculating unit 200 for calculating channel property information inclusive of a signal to noise rate and calculating a beam coefficient for forming a beam in a configuration optimizing reception sensitivity from the channel property information, and a receiving beam processing unit 300 for outputting the signal received from the antennas to the receiving signal generating unit and controlling the corresponding antenna to form a beam in a configuration corresponding to the beam coefficient from the beam coefficient calculating unit.
