Claim:
1. A system for providing a beamforming vector, the system comprising: a transmitter associated with a plurality of cells and including at least one apparatus calculating beamforming vectors, wherein the apparatus controls a signal transmission of each of the plurality of cells; wherein the apparatus defines a probability (ψ) for an interference cancellation, expresses a network-wide sum rate as a function of ψ, calculates a value of ψ that maximizes the network-wide sum rate, calculates a range of a magnitude of an interference channel to be cancelled corresponding the value of ψ, and designs for at least one Base Station (BS) a beamforming vector that maximizes the network-wide sum rate by using the value of ψ, and a receiver receiving a signal from the transmitter using the beam forming vector and comprising at least one mobile station.
