RS分形算法matlab代码实现,即利用RS方法计算时间序列的分形hurst指数(RS fractal algorithm matlab code realization, i.e., using RS method to calculate the fractal time series hurst index)

DFT和FIR宽带波束形成源程序 可以自行设置参数 如载频强度 入射角度 信噪比等(DFT and FIR broadband beamforming source code can set the parameters such as the intensity of the incident angle of the carrier frequency signal to noise ratio, etc.)

通过BUTTERWORTH滤波器,讲语音信号中的噪声过滤掉.(By BUTTERWORTH filter, speaking voice signal in the noise filtered out.)

说明：  时频分析方法是非平稳信号处理的一个重要分支，它是利用时间和频率的联合函数来表示非平稳信号，并对其进行分析和处理，利用时频分析法对语音信号进行去噪。(Non-stationary time-frequency analysis is an important branch of signal processing, it is the joint use of time and frequency functions to represent the non-stationary signal and its analysis and processing, using time-frequency analysis of the speech signal denoising. )
