摘要
将城市室外电波传播模型、手机天线本征激励方向图以及信号合并方式相结合 ,建立了分析在具有共道干扰的多径衰落环境中手机双天线系统的性能模型。用这一模型研究了采用最优合并方式的手机上双单极子天线系统的性能 ,分析了合并性能受共道干扰强度、天线互耦以及机身的影响。
A simulation approach is presented, which combines the outdoor radio propagation model and the eigen-driven patterns of handset antenna elements and combining schemes of receiving signals, to investigate the performance of a dual antenna handset under co-channel interference(CCI) and multi-path fading environment. The performance of a dual monopole handset system with optimum combining was then studied, and the influence of co-channel interference, the mutual coupling of antenna elements and handset body is also analyzed.
