two improved competitive beamforming design schemes are proposed to maximize the worst SINR in each cell for downlink transmissions.One is the competitive design with interference control.We use different interference control factors to suppress the inter-cell interference.The other design is the competitive design with power control.We adjust the power of each base station (BS) to improve the system performance.Both the two improved designs keep the distributive nature of the competitive design and improve the worst SINR of the system.Simulation results show that the competitive design with power control outperforms that with the interference control when the transmit power increases.
