摘要
通常将物理层吞吐量作为MIMO OTA测试的性能指标,而多天线设备主要以支持数据应用为主,网络层吞吐率的测试与应用相关性更高。从多天线传输模式和MIMO OTA实现方式等方面介绍了网络层吞吐量测试的原理和方法,从工作层次、测试目的和影响对象等角度分析了物理层和网络层吞吐量的差异,通过实验结果对比和分析,说明以网络层吞吐量测试作为基于用户体验的MIMO OTA能力评估是必要的。
Generally, physical-layer throughput is used as the performance metric of MIMO OTA. However, multi-antenna device mainly supports data application and the test of network layer throughput is highly related to applications. From the aspects of multi-antenna transmission and MIMO OTA implementation mode, the principle and method of network layer throughput test are elaborated. From the perspectives of task hierarchy, test purpose and influencing factor, the difference between physical-layer and network layer throughput is analyzed. Based on the comparison and analysis of experimental results, it is necessary that the network layer throughput is used as the capability evaluation of MIMO OTA oriented to user experience.
