中文说明：针对目前双门限能量检测中存在的当判决统计量落在两门限之间时，需循环检测的问题，本文将介绍一种基于自适应双门限的能量检测算法。
English Description：
In order to solve the problem of cyclic detection when the decision statistics fall between two thresholds in the current dual threshold energy detection, this paper introduces an energy detection algorithm based on adaptive dual threshold.
