Abstract:
1. An Orthogonal Frequency Division (OFDM) receiving device for forming a beam with uneven width according to a channel property, comprising: a receiving signal generating unit for decoding and restoring OFDM signals from a plurality of antennas; a beam coefficient calculating unit for calculating channel property information inclusive of a signal to noise ratio, from signals received from the receiving signal generating unit, and calculating a beam coefficient for one of the plurality of antennas for forming a beam in a configuration that optimizes reception sensitivity from the channel property information; and a receiving beam processing unit for outputting the OFDM signals from the plurality of antennas to the receiving signal generating unit, and controlling a corresponding one of the plurality of antennas to form a beam in a configuration corresponding to the beam coefficient received from the beam coefficient calculating unit.
