Non Local InSAR filtering NL-InSAR

低通滤波器，对数据进行平滑，也叫做最小二乘法，Savitzky-Golay算法(a particular type of low-pass filter, well-adapted for data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO (Digital Smoothing Polynomial) filters. Rather than having their properties defined in the Fourier domain and then translated to the time domain, Savitzky-Golay filters derive directly from a particular formulation of the data smoothing problem in the time domain)

基于小波包分解的语音去噪，根据熵谱概率密度函数估计阈值，去除实际环境噪声。(Based on wavelet packet decomposition of the voice de-noising, in accordance with spectral entropy probability density function estimated threshold, the actual removal of environmental noise.)

用MATLAB绘制系统零极点，有关Z变换的相关知识(MATLAB zero pole system, the Z-transform knowledge)

基于dct的伪随机序列的数字图像水印，算法较为简单，鲁棒性一般，不能很好地抵御噪声攻击(Dct pseudo-random sequence-based digital image watermarking algorithm is relatively simple and general robustness against noise attack can not)

cordic算法实现特征值分解，非常实用，代码可以作为参考(cordic eigenvalue decomposition algorithm, very practical, code can be used as a reference)

基于支持回归向量机的端点延拓程序解决EMD端点效应，包括向左延拓和向后延拓。(EMD solve end effect based on support vector machine regression endpoint extension programs, including the left rear extension and extension.)

基于simulink的双馈异步风力发电机的仿真模型(Simulink simulation model of doubly-fed induction wind turbines based)

基于整数小波变换的图像无损压缩方法(Based on Integer Wavelet Transform image lossless compression method)

近年来随着移动互联网业务和物联网业务的兴起与 发展，用户对移动宽带业务需求越来越旺盛，对移动通信 网络的接入速率和质量要求也越来越高，原有基于码分多 址（CDMA）的3G及其增强技术未来将无法满足业务发展 需要，因此3GPP及3GPP2组织自2004年开始启动长期 演进（LTE）/空口演进（AIE，后改名为超移动宽带UMB）项 目，旨在通过引入一些关键技术，如正交频分复用（OFDM） 调制技术、多入多出（MIMO）技术、混合自动重传请求 （HARQ）、全IP扁平化架构及动态带宽分配等实现网络变 革，达到以下所述的网络性能，为移动宽带多媒体业务持 续发展提供技术保障。(Abstract:To meet the needs of mobile broadband services,LTE is being deployed and becoming ma－ tured,which includes key technologies such as OFDM,high-order modulation,HARQ,enhanced multi-antenna technologies,fast synchronization technologies,scalable control channel design,adap－ tive resource allocation,interference suppression technologies etc.Moreover,the discussion on LTE- Advanced has started,where technologies being considered includes aggregate multi-carrier,high－ er-order MIMO,smart relay,heterogeneous net－ work,multipoint collaboration as well as enhanced interference management.)
