| 摘 要： | 研究了MIMO通信中极化分集在移动终端的应用,通过在传统极化分集模型中加入来波的角谱分布,求解了正交极化接收的空间衰落相关性,最后用Monte Carlo法仿真了信道遍历容量随平均到达角、角度扩展以及天线偏离角的变化,并在体积受限条件下比较了空间分集和极化分集的信道容量,理论上验证了在体积受限条件下应用极化分集能较大的提高MIMO信道的传输容量.

| Abstract: | The behavior of polarization diversity in mobile terminal in MIMO communication is investigated. Formula of spatial correlation is derived for different shape of Power Azimuth Spectrum(PAS). Monte Carlo method is applied to investigate the variation of capacity for MIMO systems with average AOA, Angular Spread and polarization angle.The simulation results between using spacing diversity and polarization diversity under spatially constrained conditions are compared and show that polarization diversity is a promising approach. |
