中文摘要：
在对高铁视距SIMO（single—inputmultiple—output）下的直线多天线阵列接收进行三维建模的基础上，分析了车载Ⅳ组阵列合并接收的信道容量，发现合并后的信道容量在基站附近会得到提升，但是存在抖动，而且很快衰减到香农容量，单纯地增加接收天线阵列组数Ⅳ并不能获得平稳容量增益。研究还发现，调整阵列的参数并将阵列进行分组，适当改变每组阵列的权重值可获得稳定容量增益。计算机数值仿真结果也表明，适当的设置会使得列车在不同速度下克服驶过基站时的容量振荡，并获得平稳的信道容量。
英文摘要：
Based on the three-dimensional modeling of line-of-sight SIMO （single-input multiple-output） channel for high-speed railway, which adopts uniform hnear receiving array, the channel capacity of N-group receiving arrays was analyzed. The combining capacity grows but vibrates near base station and fails to Shannon capacity quickly. Instead of increasing group numbers of receiving arrays Simply, stable capacity can be obtained by adjusting array parameters, grouping arrays and changing array weights among groups. The computer simulation results illustrate that proper setting would get stable channel capacity and avoid oscillation when the train is passing through the base stations.
