New smart antenna algorithm applied to autonomous area control for mobile radio network

In this paper, we proposed applying smart antenna technology to AAC and the proposed AAC-SA method, which is a new antenna pattern control algorithm suited to AAC. The simulation results show that the proposed method automatically generates a high quality area even when the BS arrangement is random. The quality level is even equal to that when the BS arrangement is regular. In addition, the effectiveness of the method in an office environment was investigated based on a ray-tracing simulation of the propagation characteristics.
