摘　　要：从MIMO的特性出发,在全电波暗室内利用多天线探头测量方法,实现了对多天线无线设备OTA的多径环境模拟。给出了OTA多径信道模拟器的校准要求,以及验证测试环境可靠性的方法,满足了设计要求。Based on the characteristics of MIMO, a solution is given that muhipath environment simulation for OTA testing of muhipleantenna wireless devices can be performed in a fully anechoic chamber using an array of measurement antennas. The details on the calibration requirements for an OTA multipath simulator are provided as well as showing various validation test results designed to verify that the test environment is performing as expected.
