基于蒙特卡罗法2PSK系统抗噪声性能仿真 编写MATLAB的M文件，用该文件的采用相干解调法的2PSK系统的抗噪性能进行1000个符号的蒙特卡罗法仿真，画出误码率与信噪比之间的关系曲线(Based on the Monte Carlo simulation of anti noise performance of 2PSK system Write a MATLAB M file, the file by using the coherent demodulation method for 2PSK system anti-noise performance of 1000 symbols of the Monte Carlo simulation, draw the error rate and signal to noise ratio and the relation curve between the )

非常好的MATLAB教程，当你看完教程后你会发现MATLAB比其它开发语言要简单的多(MATLAB tutorial is very good, when you read the tutorial you will find MATLAB simpler than other development languages ​ ​ to)

MATLAB软件对b样条曲线曲面进行拟合(B-spline curve and surface fitting)

用matlab的simulink实现状态观测器设计及仿真，绘出state-space 模块的输出值的阶跃响应曲线以及观测器的输出值的阶跃响应曲线。(To achieve observer status with the design and simulation of matlab simulink, step response curve step response curve and observing the output value is plotted state-space module output value.)

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.
