对采用智能天线的移动通信系统的电磁干扰性能进行了分析与仿真。仿真结果表明,采用智能天线的移动通信系统可以减少对环境所造成的电磁干扰和电磁污染,并且电磁干扰是随着用户分布而变化的,是有方向性的。与采用传统全向单天线的移动通信系统相比较,采用智能天线的移动通信系统最大干扰抑制比可达14.52dB,平均干扰抑制比为6.94dB。
The electromagnetic interference performance of the mobile communication system with smart antenna is analyzed and simulated. The simulation results show that the mobile communication system with smart antenna can reduce the electromagnetic interference and electromagnetic pollution caused by the environment, and the electromagnetic interference is directional with the distribution of users. Compared with the mobile communication system adopting the traditional omnidirectional single antenna, the maximum interference rejection ratio of the mobile communication system adopting the smart antenna can reach 14.52 dB and the average interference rejection ratio is 6.94 dB.
