Abstract

The invention discloses an interference detecting and processing system and method. And the system comprises A / D converter, frequency converting unit, and extracting and filtering unit and also comprising collecting module and analyzing module, where the collecting module is used to collect the base band signal extracted and filtered by the extracting and filtering unit, make short-time energy integration on the base band signal and input the integration result into the analyzing module; the analyzing module is used to form a receiving power-time relation sequence and detect and judge whether interference exist. And it implements detection and elimination for time-sharing interference, obtaining accurate system load, reducing system mis-triggering caused by increase of total bandwidth power and assuring power control astringency.

Description

technical field

[0001] The present invention relates to the technical field of mobile communication, in particular to an interference detection and processing system and method. Background technique

[0002] Code division multiple access system, including narrowband code division multiple access (CDMA) communication system, wideband code division multiple access (WCDMA) communication system, code division multiple access 2000 (CDMA2000) communication system, time division duplex - synchronous code division multiple access ( TD-SCDMA) communication system. It is a self-interference system, which requires the reverse load to be maintained within a certain range, so that the stability of the reverse link can be guaranteed under the premise of ensuring the capacity of the reverse link, and there will be no problems due to the reverse load As a result, a large area of ​​the system is dropped, and the network is dropped.

[0003] The metric index of the above reverse load is Ξ· ...
