摘要
第五代(5th-Generation,5G)移动通信对毫米波信道模型提出了更高的要求,如支持三维(three-Dimensional,3D)多入多出(Multiple-Input Multiple-Output,MIMO)、有良好的空时连续性和时间演进特性及毫米波段仿真能力等.第三代合作伙伴计划(3rd Generation Partnership Project,3GPP),推荐准确定性无线信道产生器(Quasi-Deterministic Radio Channel Generator,QuaDRiGa)为5G首选仿真平台,但目前尚无开展QuaDRiGa仿真平台在毫米波段的仿真验证成果.本文基于26GHz的毫米波段室外微蜂窝场景下的视距与非视距实测数据,在大尺度信道参数统计和时间演进特性两方面开展了对QuaDRiGa平台的仿真验证.结果表明,QuaDRiGa仿真结果与实测数据能够很好地吻合,验证了QuaDRiGa仿真模型在毫米波段的适用性.
The fifth generation mobile communication（5G） puts forward higher requirements on chan- nel model such as the capability for millimeter wave band simulations, supporting three-dimensional （3D） MIMO and having better space-time continuity and time evolution. Quasi-deterministic radio channel gen- erator （QuaDRiGa） was recommended as the preferred simulation platform for 5G by 3GPP. However, so far there were no published results on QuaDRiGa verifications in millimeter wave bands. In this paper, based on the outdoor microcellular line-of-sight and non-line-of-sight channel measurements at 26 GHz, the QuaDRiGa platform is verified by the statistics of large scale parameters and channel time evolution. It is shown that the simulation and measurement results have good agreements, which verifies the applicability for QuaDRiGa in millimeter waves.
