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