这是关于va检测的程序。 仿真参数为: 帧数：1000 帧长：100 调制方式：bpsk 信道：3径rayleigh慢衰落信道 接收：VA检测 文件有：bpsk.m；dec_bpsk.m；trellis.m；viterbi_my.m；main.m(This is about the va testing procedures. Simulation parameters: number of frames: 1000 Frame Size: 100 Modulation: bpsk Channel: 3 Path slow rayleigh fading channel receiver: VA inspection documents: bpsk.m dec_bpsk.m trellis.m viterbi_my.m main.m)

包括两个文件，一个RLS、一个多维RLS算法matlab程序。(Consists of two files, one RLS, RLS algorithm matlab a multidimensional process.)

基于IIR滤波器的costas环的simulink实现，区别于不同的costas环，可以实现通信系统的载波同步，可以直接在matlab上打开实现，对于通信系统的同步问题的学习和设计(IIR filter based on simulink realization of costas loop, different from the various costas loop, carrier communication system can be achieved simultaneously, you can open directly in matlab implementation, the synchronization of communication systems for the study and design)

文中的方法是把图像分块，小波分解得到低频分量、高频分量，然后计算每一块的对比度，把图像块划分为清晰块、模糊块，把清晰块和模糊块相邻的区域定义为边界区域，融合时，直接选取清晰块作为融合后的相应块，对于边界区域，在小波分解的基础上采用基于对比度的像素选取的方法进行处理。(Paper, the method is to image segmentation, wavelet decomposition are low frequency, high frequency components, then calculate the contrast of each piece, the image block is divided into clear blocks, fuzzy block, to clear blocks and fuzzy block is defined as the border region adjacent to area, integration time, a clear block directly select the corresponding block as a fusion, for the border region, the wavelet decomposition on the basis of the pixel-based contrast method selected for processing.)

分析并实现了奇异谱斜率的方法，编程实现了时域信号的检测。(And to achieve a singular spectrum analysis method of slope, programming of the time-domain signal detection.)

实现单稳触发功能，扩展输入信号为指定时常(a implement of mono，expand the input signal to a given time)

接收部分从信道接收信号。经基带滤波、短码解扩、沃尔什解调、解扰、去交织和维持比译码，输出解调后的信号。各通信模块和发射机的相关模块设计类似。(Receiving part receives signals from the channel. The baseband filtering, short code solution extender, Walsh demodulation, cross talk, go to interweave and solution than decoding, maintain the output signal after demodulation. Various communication module and the related module design similar transmitter. )

homework 3-1 is difficult

里面包含了ICA算法和FASTICA算法，主要用于信号处理，如脑电信号，心电信号的伪迹去除。(It contains the ICA algorithm and FASTICA algorithm, mainly used for signal processing, such as EEG, ECG artifact removal.)

这个程序是matlab程序，进行结构有限元分析，非常有用！！！(This program is a matlab program, the structural finite element analysis, very useful!!!)
