Embodiment Construction

[0038] In the embodiment of the present invention, the position and polarization of the optimal sensitivity of the first module of the terminal on the designated channel of the test frequency band are determined, and the downlink power in the channel interval corresponding to the designated channel is determined; Measure the radiation intensity on the designated channel of the test frequency band, select the strong interference frequency point to be tested on the designated channel of the test frequency band; According to the position and polarization of the optimal sensitivity of the first module on the designated channel of the test frequency band, the corresponding downlink power , And the strong interference frequency point of the second module on the designated channel of the frequency band to be tested, to obtain the total omnidirectional receiving sensitivity of the first module under the interference of the second module and the total omnidirectional receiving sensitivity...

Abstract

The present invention discloses a mutual interference rapid test method. The method comprises: determining the optimal sensitivity position and the polarization of the first group module of a terminal on the assigned channel of a test section, and determining the downlink power of a channel section corresponding to the assigned channel; selecting strong interference frequency points to be tested on the frequency range assigned channel to be tested according to the radiation intensity of the second module group of the terminal on the assigned channel of the frequency range to be tested; and obtaining the difference of the total omnibearing receiving sensitivity of the first module group under the interference of the second module group and the total omnibearing receiving sensitivity without the interference according to the optimal sensitivity position and the polarization of the first group module of the terminal on the assigned channel of the test section, the corresponding downlink power and the strong interference frequency points of the second module group to be tested on the frequency range assigned channel to be tested. The present invention further discloses a mutual interference rapid test system.

Description

Technical field [0001] The invention relates to wireless communication technology, in particular to a method and system for rapid testing of mutual interference. Background technique [0002] At present, mobile communication terminals support more and more standards, and there are more and more communication forms of terminals, including not only GSM, TDS-CDMA, WCDMA, TD-LTE, LTE FDD, WLAN and other standards, but also various standards. At the same time, work is becoming more and more common. This leads to multiple mutual interference scenarios when working between different communication standards within the terminal. Mutual interference is the interference of the out-of-band radiation signal of the transmitting mode to the receiving mode caused by the terminal working in two modes at the same time. The current typical mutual interference test scheme is described as follows: [0003] Such as figure 1 As shown, the communication connection between the interfered cell and the te...
