摘要
基于短时分形维数的模糊控制滤波方法,对语音信号中的噪声进行滤波。该方法提出了网格分形维数和短时分形维数的新算法,并讨论了模糊控制滤波方法中的模糊控制参数的选取算法。基于虚拟仪器(Ⅵ)LabVIEW6.i平台上对语音信号进行仿真,结果表明,该方法滤波良好。
Based on the method of short time fractal numbers fuzzy control filter,to noise in the speech signal is calculated. That method bring upped new algorithm of network fractal numbers and short time fractal numbers, and fuzzy control parameter is discussed. In virtual instrument （VI） LabVIEW 6. i software workbench, combined with virtual instrument processing, which realizes real-time detection system of the speech signal. Result shows that the method is feasible and effective.
