SYSTEM FOR PROVIDING BEAMFORMING VECTOR, DEVICE FOR PROVIDING SAME, METHOD FOR PROVIDING SAME, COMPUTER PROGRAM FOR PERFORMING SAME, AND RECORDING MEDIUM HAVING SAME RECORDED THEREIN

摘要

The present invention relates to a system for providing a beamforming vector in a high density small cell environment, a device for providing the same, a method for providing the same, a computer program for performing the same, and a recording medium having the same recorded therein. To this end, the system comprises: a transmitting end consisting of a plurality of base stations, and including a beamforming vector providing device for controlling transmission of signals of each of the base stations; and a receiving end for receiving the signals transmitted from the transmitting end, and including at least one terminal unit. The beamforming vector providing device defines which is a probability in which an interference channel is removed from a terminal unit by a plurality of base stations, expresses a network-wide average transmitting rate as , calculates a value of which maximizes the average transmitting rate, and obtains a range of interference channel to be removed corresponding to . Accordingly, calculation does not have to be repeatedly performed to find an optimal beamforming vector, and an average transmitting rate which is close to an optimal state may be obtained in a one-shot method.;COPYRIGHT KIPO 2016
