在受干扰条件下，单一特征的频谱感知方法检测性能下降，且感知错误率升高无法满足频谱感知的基本要求。通过综合双阈值能量感知和分形盒维数感知在不同条件下使用的优点以解决干扰条件下的频谱感知问题，可以提升检测性能并降低感知错误率。仿真结果表明，综合特征频谱感知方法比使用两种单一特征的频谱感知方法检测性能有所提高，且感知错误率更低，在信道受干扰时具有更好的感知性能。

The single feature spectrum sensing method is low in detection performance under inferential conditions,and moreover,the rise of its sensing error rate would make this method fail to meet the basic re-quirements of spectrum sensing. By integrating the advantages of both double-threshold energy and fractal-box dimension sensing method to solve the problem of spectrum sensing, the detection performance world increase and the sensing error rate decline. The simulation results show that the sensing performance of comprehensive features spectrum sensing method is better than that of single-feature spectrum sensing method in an interfered channel.
