摘要
本文介绍了数字波束形成和发射数字多波束技术的原理和实现方法。智能天线技术可以在提高通信容量和质量的同时而不用占用更多的频谱资源。理论分析和仿真结果表明,该数字多波束形成方法具有空间分辨率高,同信道干扰可控,且计算量小,鲁棒性好等优点,有较强的实用性。
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.
