The Optimum Design of Multi-user Digital Beamforming in the Smart Antenna System
The technology and theory of downlink multi-user digital beamforming is given in this paper,smart antenna technology give a solution for the increasing capacity and quality demands for mobile communication services without a corresponding increase in RF spectrum allocation.The theoretical analysis and the result of simulation show that,compared with other methods, this method has clear advantages of higher spatial resolution,controllable co-channel Interference,lower computational complexity,better robustness,so it is more practical.
