摘要
针对EMD中端点效应的问题,利用最小二乘支持向量回归机的预测特性对信号两端进行预测,从而对端点效应进行抑制。通过对仿真信号进行分析,探讨了端点延拓处理后的Hilbert谱。
In this paper, regarding the problem of EMD end effect, using the least square support vector re- gression, it could predict the signal＇s ends to inhibit the end effect, the Hilbert spectrum after Endpoint ex- tension is discussed based on the analysis of simulation signal.
