Abstract

The invention discloses a space radio-frequency performance test method and a system in a multi-antenna system. More than two antennas are arranged on a dark absorbing chamber; a base station simulator is controlled to send a reference test signal to a device to be tested through a channel simulator and an antenna; when the reference test signal is determined to not satisfy set requirements, the reference test signal is adjusted until the set requirements are satisfied; corresponding test cases are determined according to different channel models; signal simulation is implemented by a channel emulator on the test signal outputted by the base station simulator, and then the test signal is sent to the device to be tested through the antenna; each radio-frequency performance of the device to be tested after the receiving of the test signal is tested according to the radio-frequency performance test items corresponding to the test cases; and when all the radio-frequency performances reach the standard, the space radio-frequency performance reaches the standard. The invention also discloses a space radio-frequency performance test system in the multi-antenna system. The invention is simple to realize and has lower cost.

Description

technical field [0001] The invention relates to antenna testing technology, in particular to a space radio frequency performance testing method and system in a multi-antenna system. Background technique [0002] With the development of modern industry, all kinds of wireless communication products can only guarantee the quality of communication if they have good transmission and reception performance. The indicators to measure the transmission and reception performance include total radiated power (TRP, Total Radiated Power), total radiation sensitivity (TRS, Total Radiated Sensitivity) and space radio frequency performance (OTA, Over The Air), etc., among them, TRP must be higher than a set threshold to meet the corresponding communication requirements, and TRS must be lower than a set threshold, TRP and TRS are both satisfied When setting the threshold, the value of TOA means that the test index is good. [0003] In order to ensure the normal use of mobile terminal equipme...
