利用功率谱估计及ＩＦＴ数字滤波及短时傅里叶变换等手段对声音信号进行处理(Use of the means of power spectrum estimation and IFT digital filtering and short time Fourier transform , such as the sound signal processing )

序列进行离散傅里叶级数变换，画出相位图，频谱图。改变序列长度，然后重复上述过程(Sequence of discrete Fourier series transform, draw the phase diagram, spectrogram. Change the length of the sequence, and then repeat the process)

分别利用fisher判别法和近邻法对一组声呐数据进行模式识别，计算分类的正确率(Respectively, and the use of fisher discriminant method nearest neighbor method sonar data to a set of pattern recognition, to calculate the correct classification rate)

说明：  光伏发电功率主要受太阳辐照度影响，所以准确预测太阳辐照度对光伏功率预测十分重要。程序采用小波分解先对辐照度数据进行分解，然后再用bp神经网络对分解的辐照度数据分别预测，再组合作为最后的预测结果。(Photovoltaic power generation is mainly affected by solar irradiance, so accurate prediction of solar irradiance is very important for photovoltaic power prediction. The program uses wavelet decomposition to decompose the irradiance data, then uses BP neural network to predict the decomposed irradiance data separately, and then combines them as the final prediction result.)
