估算带宽，先是计算输入信号单边带功率谱密度，然后估算出信号所占的带宽(Bandwidth estimation, first calculating the input signal is single sideband power spectral density, and then estimate the proportion of signal bandwidth)

matlab环境下计算MFCC参数（mel倒谱参数），lpcc参数（线性预测倒谱）和pitch（基因）(calculate mfcc lpcc pitch )

本工具包给出了PDE常见的求解方法程序。PDE数值求解应用相当广泛。(The kit gives the common method for solving PDE program. Numerical Solution of PDE has been widely used.)

产生一个线性调频信号用于探测在固定距离上的目标的存在性，回波中加上复高斯白噪声，采用CA-CFAR方法检测得到图形(A chirp signal used to detect targets at a fixed distance the existence of echoes plus complex Gaussian white noise, the use of CA-CFAR method of detecting get graphic)

matlab实现pcm编码，是信号模数转换的编码方式的实现(matlab coding to achieve pcm is the signal analog-digital conversion of the realization of the encoding)
