Abstract

The invention discloses an obstruction index test method, a device and a system. The method comprises steps that: on the condition that no obstruction interference signal is emitted by an interference signal antenna, sensitivity of detected equipment for receiving a useful signal emitted by a useful signal antenna is determined and is taken as non-interference sensitivity; on the condition that intensity of each obstruction interference signal emitted by the interference signal antenna increases gradually, sensitivities of the detected equipment for receiving each useful signal emitted by the useful signal antenna are determined and are taken as interference sensitivities; compared with the non-interference sensitivity, when the interference sensitivity decreases to a preset sensitivity threshold, signal intensity of an obstruction interference signal presently emitted by the interference signal antenna is determined and is taken as an obstruction index value of the detected equipment. The method improves accuracy for testing an obstruction index.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a blocking index testing method, device and system. Background technique [0002] At present, in the field of wireless communication technology, in order to conduct a more comprehensive detection of the performance of communication equipment in order to better use the communication equipment, it is usually necessary to test the blocking index of the communication equipment. The blocking index of a communication equipment can reflect the communication The anti-interference performance of the equipment, that is, the ability to receive useful signals in the presence of interfering signals. [0003] In the prior art, the blocking index test of communication equipment is carried out by using the method of wired conduction test. The schematic diagram of the network is as follows figure 1 As shown, the components are connected by wires, and the test process is as follows...
