Embodiment Construction

[0021] A method for realizing the spatial radio frequency performance test of multi-antenna equipment of the present invention can be applied to OTA testing of multi-antenna equipment and systems, refer to figure 1 As shown, it mainly includes the following steps:

[0022] Step 101: Obtain the performance parameters of each antenna of the device under test;

[0023] Specifically, the radiation pattern of the far-field antenna can be measured by using an existing darkroom to obtain the required performance parameters for evaluating the performance of the antenna.

[0024] Here, the measured performance parameters of each antenna include parameters such as radiation power of each antenna, antenna efficiency, etc., and a correlation coefficient between any two antennas.

[0025] Step 102: According to the measured performance parameters of each antenna, reset the parameters of the channel simulator used to simulate the spatial channel;

[0026] Step 103: complete the link emula...

Abstract

The invention discloses a method for testing a space radio frequency performance OTA of multi-antenna device. The method comprises the following steps of: resetting the parameters of a channel simulator for simulating a space channel by the performance parameters of each antenna of a detected device obtained through the existing darkroom measurement method; using the reset channel simulator to complete the linkage simulation or the linkage testing of the detected device to finally obtain an OTA testing result of the detected device. The invention further discloses a system for testing space radio frequency performance of multi-antenna device. A new idea for realizing the OTA testing of a MIMO system or a MIMO terminal in two stages through successive steps is offered; the testing can be completed by using a traditional darkroom without reforming; and the testing is low in difficulty and easy to realize.

Description

technical field [0001] The invention relates to radio frequency test technology of wireless communication products, in particular to a method and system for realizing space radio frequency performance test of multi-antenna equipment. Background technique [0002] With the development of modern industry, all kinds of wireless communication products need to have good transmitting and receiving performance, namely: the total radiated power (TRP, Total Radiated Power) should be higher than a certain value, and the total radiated sensitivity (TRS, Total Radiated Sensitivity) should be It is lower than a certain value, that is to say, the space radio frequency performance (OTA, Over The Air) test index must be good to ensure the communication quality. [0003] In order to ensure the normal use of mobile terminal equipment in the network, the Cellular Telecommunications and Internet Association (CTIA) has formulated the test standard for mobile station OTA performance (The test pla...
