A multi-antenna device space performance verification method and system thereof

Abstract

The invention discloses a space performance verification method of a multi-antenna device. The space performance verification method of the multi-antenna device comprises for transmission impact factors of a system, inputting information to be tested and reference information of the first transmission impact factor of the transmission impact factors of the system into the system, and inputting reference information of the other transmission impact factors into the system; obtaining a first test result according to the information to be tested of the first transmission impact factor and the reference information of the other transmission impact factors; obtaining a second test result according to the reference information of the first transmission impact factor and the reference information of the other transmission impact factors; verifying the performance of the current first transmission impact factor by means of the two test results. The invention further discloses a space performance verification system of the multi-antenna device. According to the technical scheme of the space performance verification method and system of the multi-antenna device, the flexible conversion of interfaces and multilevel multidirectional evaluation can be achieved, the accuracy of performance test results of the system can be improved, the improvement of design proposals or network optimization is facilitated, and the performance of the multi-antenna device is improved.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a multi-antenna device space performance verification method and system thereof. Background technique [0002] Single-antenna OTA (OvertheAir) test is an active test, mainly to test the total radiated power (Total Radiated Power, TRP) and total omnidirectional sensitivity of the terminal in the free space, human head model and left and right ears in the microwave anechoic chamber These two indicators (TotalIsotropicSensitivity, TIS) directly reflect the radiation performance of the terminal machine in all directions in three-dimensional space, and provide a basis for quantitative analysis and optimization of the impact of the human body on the radiation performance of the terminal machine. Manufacturer's attention and recognition. [0003] With the advent of the 4G era, multi-antenna technology is widely used in various wireless communication products. Since multi-antenna tec...

Problems solved by technology

[0003] With the advent of the 4G era, multi-antenna technology is widely used in various wireless communication products. Since multi-antenna technology largely relies on complex multi-path channels, the previous single-antenna OTA test method can no longer meet the requirements of multi-antenna. RF Testing Needs

[0004] At present, the over-the-air test of multi-antenna equipment is to test terminal equipment (such as mobile phones, antennas) through the channel emulator module in the multi-antenna OTA darkroom environment, but it is impossible to realize multi-level and multi-level multi-level multi-antenna equipment space performance.
