Self-adaptive isolation measuring system in repeater

The invention provides an isolation measuring system for a repeater in a wireless system. The repeater provided by the invention comprises an antenna 1, an antenna 2, a control module and a processing module, wherein a training sequence is generated and processed by the repeater to automatically measure the antenna isolation of the repeater, and a measuring strategy is self-adaptively adjusted through changing the repeating frequency of the training sequence; moreover, in the invention ,a repeating sequence of a Golay sequence is used as the training sequence. By using the invention, the antenna isolation of the repeater is convenient for workers to measure, the isolation measuring speed is increased, and through the self-adaptive adjustment of the measurement, the antenna isolation can be measured by using comparatively less resources and comparatively higher speed under the situation of good channel condition and the measuring strategy can be also adjusted under the situation of severe channel condition to
