Problems solved by technology

[0005] Although the above method can identify the interference signal in the disturbed system, it requires testers to analyze a large amount of data output by the scanner point by point, and the data of a frequency scan of the scanner usually lasts more than ten hours, and the amount of data is large. This manual operation method makes the method time-consuming, laborious, and the accuracy cannot be guaranteed

Embodiment Construction

[0055] When LTE is used as the disturbed system, the biggest sources of interference come from blocking interference, co-channel interference, and spurious interference. Wherein, the spurious interference includes: harmonic interference, intermodulation interference, and the like. When the LTE works in the F frequency band, the same-channel interference source is TD-SCDMA. In addition, interference sources also include other interferences that cannot be avoided during communication transmission.

[0056] Embodiments of the present invention describe a method for identifying interference signals in an LTE system, such as figure 1 As shown, the method includes:

[0057] Step 11: Divide the scanning signal with the LTE working bandwidth at the current scanning moment into at least two sub-bands Sn.

[0058] Wherein, n is the number of divided sub-bands, which is a positive integer and n≥2.

[0059] In the technical solution recorded in the present invention, the scanner outpu...

Abstract

The invention discloses an identification method for an interference signal in an LTE system. The method includes the steps of dividing a scanning signal provided with LTE work bandwidth at the current scanning moment into at least two sub-bands, determining the type of interference on the at least two sub-bands, and determining the type of interference on the scanning signal at the current scanning moment according to the type of the interference on the at least two sub-bands. Meanwhile, the invention further discloses an identification device of the interference signal in the evolution LTE system. According to the identification method for the interference signal in the LTE system, automatic identification of the interference signal in the LTE system can be achieved, and therefore manpower and material resources are saved.

Description

technical field [0001] The present invention relates to an identification technology of an interference signal in a communication system, in particular to a method and a device for identifying an interference signal in a Long Term Evolution (LTE, Long Term Evolution) system. Background technique [0002] Wireless communication technologies include the following: LTE, Global System For Mobile Communication (GSM, Global System For Mobile Communication), Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division Synchronous Code Division Multiple Access), Code Division Multiple Access (CDMA, Code Division Multiple Access), and Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access), etc. [0003] Due to the limitation of spectrum resources and the similarity of network topology, the above-mentioned communication systems have the same working frequency band. Here is an example: when LTE is used as the main system (disturbed s...
