摘要
提出一种双极化天线的系统级建模方法,以解决TD-HSPA+系统中极化性能研究无准确天线模型的问题。并通过结合多天线方案中的PARC和S-PARC方案,对TD-HSPA+下行系统性能进行了仿真分析和研究,重点对比了市区宏小区和郊区宏小区等场景下的双极化天线配置和传统线阵天线配置性能差异。系统级仿真结果表明,在覆盖半径较小的市区,利用双极化天线组网能提供良好的系统性能,提高小区容量。
A dual-polarized antenna modeling methodology was proposed for system-level simulation, which is used to resolve the problem that no accurate antenna modeling method is available for the evaluation of antenna polarization effect in the TD-HSPA＋ system. Downlink performance was investigated and analyzed for PARC and S-PARC multiple antenna schemes, and the performance between traditional uniform linear antenna and dual-polarized antenna was compared in the scenarios of urban and suburban. The system-level simulation results show that dual-polarized antenna configuration can improve cell throughput in the urban scenario with small cell size.
