Title:
FOUR-DIMENSIONAL OVER-THE-AIR PERFORMANCE TEST METHOD FOR DYNAMIC SCENE CHANNEL
Document Type and Number:
WIPO Patent Application WO/2023/284521
Kind Code:
A1
Abstract:
Disclosed is a four-dimensional over-the-air (OTA) performance test method for a dynamic scene channel, comprising: constructing a time-domain non-stationary dynamic scene channel model; selecting, in a four-dimensional multi-probe anechoic chamber (4D-MPAC) test system, an OTA probe the quantity, positions and power weights of which are suitable by means of a probe selection algorithm; and finally, constructing a 4D-MPAC dynamic channel test system of a target channel in a DUT test area, thus contributing to solving OTA performance test problems of current time-domain non-stationary channels. The aim of the present invention is to provide a 4D-MPAC method for a dynamic scene channel, which may effectively and accurately reproduce a target dynamic scene channel model in an anechoic chamber by constructing a dynamic scene channel model while reducing as much as possible the costs of a test system, and an index for determining the construction accuracy of the dynamic scene channel model is provided.
