Abstract
Disclosed are a method and device for detecting a standing-wave ratio, which are used for realizing quick and accurate detection of the standing-wave ratio by only using a downlink service signal transmitted by a TD-LTE base station system, thereby preventing a special training sequence from causing additional interference to the base station system. The method comprises: capturing output power detection data (OPD) of a service signal transmitted by the base station system and reflection power detection data (RPD) of a device to be detected in a base station; within a first preset bandwidth range, respectively extracting feedback signals of the OPD and feedback signals of the RPD within a plurality of periods of time according to a preset data length; determining spectrum characteristics of the feedback signals of the OPD and spectrum characteristics of the feedback signals of the RPD respectively corresponding to each period of time, and determining the reflection coefficient of the base station system according to the spectrum characteristics of the feedback signals of the OPD and the spectrum characteristics of the feedback signals of the RPD respectively corresponding to each period of time; and determining the standing-wave ratio of the base station system within the first preset bandwidth range according to the reflection coefficient of the base station system.
