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.
In addition, the existing laboratory interference test methods for general mobile communication terminals cannot truly restore the interference test in the ITS scenario, and are not suitable for the interference test of ITS terminals

Abstract

The invention provides a wireless interference test method and system. The wireless interference test method that is used for carrying out semi-physical simulation interference testing in an anechoicchamber environment comprises: a wireless interference test system including a transmitting unit, an anechoic chamber, a receiving unit, and an interference device is established and communication links between all devices in the wireless interference test system are established; and when wireless interference testing is carried out, different parameters of a channel simulator in the transmittingunit are set to simulate real channels of different scenes in the test frequency band. Therefore, problems of lots of manpower and time costs for common outer field testing are solved, so that the testing efficiency and effectiveness are improved substantially. Moreover, because the outer field test interference source has attenuation and declining problems and an interference signal arriving at the under-interference device can not be quantified easily, interference sources with different frequency bands are added by a standard antenna in the anechoic chamber, so that the testing time is shortened effectively and the testing accuracy and reproducibility are improved.

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...
