OFDM receiving device and method for beam forming with uneven beam width based on channel properties |
摘要 |
<p>An OFDM receiving device for adjusting a beam formation azimuth through a plurality of antennas (510,550): includes a receiving signal generating unit (100) for decoding and restoring OFDM signals from the antennas (510,550), 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 controlling the corresponding antenna (510,550) to form a beam in a configuration corresponding to the beam coefficient from the beam coefficient calculating unit. When the device is to also operate in a transmission mode, a transmitting signal generating unit (600) for modulating a transmission-intended signal into a transmitting signal, and a transmission beam processing unit (700) for controlling the antenna according to the beam coefficient from the beam coefficient calculating unit are also provided. As a result, a beam configuration of the antenna can be flexibly changed by calculating the beam coefficient from the detected signal during the decoding of a receiving signal, thereby improving accuracy of the receiving signal. In addition, when a signal is transmitted by the beam formed by the beam coefficient calculated from the receiving signal, a direction of a receiving unit receiving the transmission-intended signal is considered to improve accuracy of the transmitting signal. <IMAGE></p> |
