An OFDM receiving device for adjusting a beam formation azimuth through a plurality of antennas, a communication device using the same, and a method thereof. The OFDM communication device having a plurality of individually-aligned antennas includes a receiving signal generating unit for decoding and restoring OFDM signals from the plurality of antennas, a beam coefficient calculating unit for calculating channel property information inclusive of a signal to noise rate, from the signal received from the receiving signal generating unit, and calculating a beam coefficient of an antenna, for forming a beam in a configuration that optimizes reception sensitivity, from the channel property information, a receiving beam processing unit for outputting the signals 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 received from the beam coefficient calculating unit, a transmitting signal generating unit for modulating a transmission-intended signal into a transmitting signal, and a transmission beam processing unit for controlling the antenna according to the beam coefficient from the beam coefficient calculating unit in order to transmit the transmitting signal through the antenna.

Orthogonal frequency division multiplexing (OFDM) receiving device for forming beam with uneven width by channel property, communication device using the same, and method thereof
