移动通信中多波束智能天线性能的研究

内容简介：研究了移动通信环境下的多波束智能天线，并基于统计传播的同信道干扰模型，分析了快衰落及慢衰落情况下未采用多波束智能天线与采用多波束智能天线时的中断率，并进行了比较. 计算机仿真结果表明：采用多波束智能天线，不论在单个同信道小区还是多个同信道小区情况下，系统的中断率将随着波束数的增大而降低.

Abstract：Multibeam base-station smart antennas are discussed in this paper.We analyze the outage probability of mobile communication system suffering both fast fading and shadowing by means of statistical propagation model, and contrast the case that adopt multibeam smart antennas to the case that adopt omnicase.The results emulated by computer show that the outage probability of mobile communication system will diminish as the increasing of the number of beams using smart antennas no matter when suffering a single co-channel interfence or six ones.
