摘要： The present invention relates to the communication field and provides method and system for detecting repeater self-excitation and the repeater using the method and system. The method includes detecting an output power of an up link; judging whether the detected output power of the up link exceeds a threshold of self-excitation and, if so, adding a numerically-controlled attenuation to the up link accordingly; and judging whether the change in the output power of the up link is equal to that in the numerically-controlled attenuation and, judging whether the repeater is subject to a self-excitation according to the result of judgment regarding the change in the output power of the up link. The repeater self-excitation detecting method has the following advantages: 1. The self-excitation can be detected in time, thus avoiding had effect on the communication system; 2. The devices of repeater can be protected from being burned down; and 3. The cost incurred by the patrol inspection personnel can be reduced.
