高效的MIMO OTA双通道测试方法

现代的无线通信技术如LTE,HSPA＋和WiMAX,都采用MIMO（多输入/多输出）技术实现了数据传输速度的提高。相应地,天线测试系统（OTA）也同样需要升级到支持MIMO的测试模式。本文介绍了用一种简单而且经济的测试方法来验证MIMO设备的OTA性能,包括各向同性灵敏度（EIS）和吞吐率。

Effcient MIMO OTA Dual-channel Testing Method

Modern wireless communication technologies such as LTE,HSPA＋ and WiMAX include the MIMO technology to achieve increased speed for data transmission.Existing Over-the-air（OTA） test systems need to be upgraded to support MIMO as well.This white paper summarizes a straightforward and cost-effective approach to verify the OTA performance of MIMO-enabled devices,like measurements of the effective isotropic sensitivity（EIS） and of obtained throughput.
