基于FFT变换、DCT变换、HT变换、小波变换和矢量量化技术的图像压缩的Matlab实现。(Based on the FFT transform, DCT transform, HT transform, wavelet transform and vector quantization image compression technology, the Matlab implementation.)

This is a MATLAB Simulation for obtaining conduction and switching losses in Three-Phase OHSW(optimized harmonic stepped wafeform) cascaded 9-level inverter.The simulation has been done in several SUBSYSTEMS.The first one produces switching functions based on OHSW.The second one is the 9-level inverter model.the third and fourth obtain load and switching devices currents respectively.The fifth and sixth obtain switching and conduction losses.

基于最差性能最优的稳健波束形成算法可以等价转换成加载样本矩阵求逆(LSMI)算法.提出了 一种新的求解方法, 准确地计算出Lag range 乘数, 给出了LSMI 算法中的最优加载量, 解决了对角加载技术中加载量估计难题.(The robust adaptiv e beamformer using w orse-case performance optimization can be converted to the loaded sample ma trix inv ersion (LSMI) algorithm equivalently.For the LSMI beamformer , a no vel method is develo ped to so lve the precise Lagrange multiplier , and the o ptimal loading level can be computed exactly.Most important, this method gives the efficient solution to finding the optimal loading level for diagonal loading.)

该程序主要是利用matlab采集一个正弦波信号，这个正弦信号时加偏置的，然后将其转换成16进制，最后输出到txt文本当中。(In order to finish this task that we should be used for matlab program that it can let a sin. signal convert to hexadecimal and this singal add offset.The data ouput to txt.)

自己写的Gabor方程函数，可以用来产生过完备的稀疏表示字典。(Gabor write their own equation function, can be used to generate the sparse representation over-complete dictionary.)

说明：  此书《独立分量分析的原理与应用》是一本非常好的书，适合通信，声纳，地震等等从事这方面研究的技术人员。(The book, &quot Independent Component Analysis Theory and Application&quot is a very good book, for communications, sonar, seismic research in this area and so the technical staff.)
