能使桌面上不停的换色.请先生成EXE再运行不然会出错。(Enable non-stop for the desktop color. Please re-run the EXE generated will not go wrong.)

the code for four bit qpsk with 90 degrees phase shift with constellation and without constellation of noise is given

qr分解的c语言程序,可以嵌入matlab使用(simulated decomposition of the c language program, can be embedded using Matlab)

这是用matlab语言编写的程序，主要应用于对GPS观测文件的读取。(This is a program written in matlab language, mainly used to read files on the GPS observations.)

利用滑模变结构实现对倒立摆的控制仿真，采用s函数编写，便于修改(The use of sliding mode control to achieve inverted pendulum simulation, using s function to write, easy to modify)

图1为均衡带限信号所引起失真的横向或格型自适应均衡器(其中横向FIR系统长M=11), 系统输入是取值为±1的随机序列，其均值为零；参考信号；信道具有脉冲响应： 式中用来控制信道的幅度失真(W = 2～4, 如取W = 2.9,3.1,3.3,3.5等)，且信道受到均值为零、方差(相当于信噪比为30dB)的高斯白噪声的干扰。试比较基于下列几种算法的自适应均衡器在不同信道失真、不同噪声干扰下的收敛情况(对应于每一种情况,在同一坐标下画出其学习曲线): 1）横向/格-梯型结构LMS算法 2）横向/格-梯型结构RLS算法 并分析其结果。(Figure 1 is a band-limited signal caused balanced horizontal or lattice distortion adaptive equalizer (FIR system in which the lateral length M = 11), the system input is the value of a random sequence of ± 1, mean zero reference signal channel has impulse response: Wherein the amplitude of the distortion for the control channel (W = 2 ~ 4, and so as to take W = 2.9,3.1,3.3,3.5), and subjected to a channel with zero mean and variance (equivalent SNR is 30dB) Gaussian white noise. Compare the following types of algorithm-based adaptive equalizer in a different channel distortion, the convergence of different noise interference (corresponding to each situation, draw their learning curve in the same coordinate): 1) landscape/grid- LMS algorithm ladder structure 2) landscape/grid- RLS algorithm ladder structure And analyze the results.)

实现了最低有效位LSB水印算法。 压缩文件中含有原图，可直接放到Matlab中运行。(We realize the least significant bit （LSB） watermarking algorithm. It contains all the images you need,and it can be run directly in Matlab.)
