Abstract

The invention provides an interference detection method of a multi-antenna TDD (Time Division Duplex) system, which comprises the following steps of inputting a radio-frequency signal received by an intelligent antenna into a calibration channel in a remote radio module, processing the radio-frequency signal with the calibration channel, obtaining a processing result of the radio-frequency signal, and determining a corresponding parameter of the radio-frequency signal according to the processing result. The invention further provides an interference detection device of the multi-antenna TDD system. The interference detection method and the device of the multi-antenna TDD system can realize convenient and quick detection of radio frequency interference from the outside, so that blocking removal of a receiving end is facilitated, external interference removal by a network optimization mode is facilitated, the problems of manpower waste and low efficiency in an interference detection means in the prior art are solved, and the support is provided for subsequent network optimization.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, the present invention relates to an interference detection method and device for a multi-antenna TDD system. Background technique [0002] In recent years, due to the advantages of low cost, strong environmental adaptability, and convenient construction of distributed base stations, the architecture of wireless communication systems is rapidly developing towards distributed base stations, especially in the 3G mobile network currently under construction. Base stations have been widely used. [0003] The data service is the core service of the 3G network, and the bandwidth occupied by the data service is dozens or even hundreds of times that of the voice service. 3G network provides many new services for end users, including video telephony, video streaming, games, MMS, E-mail, Web and so on. As 3G network construction enters a period of rapid development, op...
