BEAM FORMING DEVICE AND METHOD CONTOLLING POWER

摘要

PURPOSE: A beam former device and an electric control method are provided to prevent the case of generating the distortion of a signal due to other user interference signal and reducing S/N ratio and S/I ratio in a random subcarrier. CONSTITUTION: A plurality of beam formers(220) is connected to each of a plurality of RX-antennas. A plurality of beam formers forms a beam by multiplying the beam forming coefficient in the receiving signal. A control unit(223) updates the beam forming coefficient to minimize the error. A control unit transfers the beam forming coefficient to the multipliers. In one receiving antenna, multipliers which have same number with the number of transmitting antennas are connected.
