System and Apparatus for Providing Beamforming Vector for Wireless Network Systems, Method, Program and Recording Media Using Thereof

摘要

The present invention relates to a system and an apparatus for providing beamforming vector for a very high density cellular networks, a method, a program and a recording medium using thereof. A transmitter that comprises a plurality of cell and an apparatus for providing beamforming vector, wherein the apparatus for providing beamforming vector controls a signal transmission of each of the plurality of cell; the apparatus for providing beamforming vector that defines a probability (ψ) of interference cancelation, expresses a network-wide sum rate as a function of ψ, calculates a value of ψ that maximizes the network-wide sum rate and calculates magnitude of canceled interference channel corresponding the value of ψ; and a receiver that receives a signal from the transmitter and comprises at least one mobile station and designs the beamforming vector that maximizes the network-wide sum rate by using ψ.
