与理论分析结果相比，小波包分析提取振动信号中的特征频率，最小均方误差等算法的MSE的计算。( Compared with the results of theoretical analysis, Wavelet packet analysis to extract vibration signal characteristic frequency, Minimum mean square error MSE calculation algorithm.)

短时傅里叶变换的实现代码，可根据自己的信号改变参数仍可实现STFT(The implementation code of STFT)

介绍了HRWS SAR成像和系统设计的一些技术环节，作为学习成像技术，这里面讲的很详细。(Introduced HRWS SAR imaging and some of the technical aspects of system design, imaging technology for learning, there is talk in great detail.)

是2014年的cnn上的一个变化的网络，将卷积层与池化层之间的线性关系变成1×1的卷积层的非线性关系，名为network in network(Is a change in the 2014 cnn on the network layer of the linear convolution and pooled into a non-linear relationship between the layers 11, convolution layer, called the network in network)

说明：  Remez滤波，BPSK复合基带信号仿真，载波生成器!(Designed to meet the following indicators, such as ripple linear phase FIR low-pass filter)

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.
