Problems solved by technology

Due to the large number of scenarios and complex combinations, it takes a lot of testing time and manpower to test all the scenarios.
At the same time, considering that the interference sources in different scenarios are also affected by factors such as path loss, shadow fading, and Doppler frequency shift, it is impossible to judge whether the interference sou

Abstract

The invention provides a wireless interference test method and system. The wireless interference test method achieves an adjustable interference test aiming at a LTE-V2X communication link in the anechoic chamber environment, comprising the following steps: establishing a wireless interference test system including a transmitting unit, an anechoic chamber, a receiving unit and an interference unitfirst; and establishing communication links between each device in the wireless interference test system to realize the semi-object simulation interference test in the anechoic chamber environment. When performing the wireless interference test, the simulation test of the true channels of different scenes in the frequency band is performed by setting different parameters of a first channel simulator in the transmission unit, therefore, the problem that more manpower and time cost are required in the general outfield test is solved, and the efficiency and effectiveness of the test are greatlyimproved. In addition, a second channel simulator is configured for the interference sources, therefore, the real interference signal characteristics in a non-used scene can be simulated, and the accurate and parameter adjustable interference source signal is realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and system for testing wireless interference. Background technique [0002] At the beginning of the 21st century, automobile technology and radio technology showed a trend of mutual integration. The proposal of ITS (Intelligent Transportation System, Intelligent Transportation System) realized the information interaction and fusion between vehicles, pedestrians and roadside infrastructure. With the popularity of LTE (Long Term Evolution, long-term evolution) technology, especially LTE-D2D (Long-Term Evolution Device-to-Device, a communication service that supports communication between devices and devices in LTE cellular systems) The formulation of the standard makes it possible to realize direct communication between vehicles, vehicles, and vehicles based on LTE technology, thereby meeting the low-latency, high-reliability communication requirements betwe...
