一个QPSK调制解调的程序，在Matlab环境下实现。(A QPSK modulation and demodulation process in Matlab environment to achieve.)

jQuery imgarea v0.9,它是一款图像裁切专用的选区插件,它本身并没有图像裁切功能,只是生成一个类似选区的虚线框,拖动四角可以调整选区大小,可以拖动整个选区移动,高亮显示被选择的图像区域，用法有很多种，具体请下载示例包，源码爱好者整理有示例文件，一看便知。(jQuery imgarea v0.9, it is a special constituency image cropping plugin, which itself does not have image cropping functionality, but dashed box generates a similar constituency, constituency size can be adjusted by dragging the corners, you can drag to move the entire selection highlight the selected image area, there are many usage details, please download the sample package, source enthusiasts have a sample file sorting, at a glance.)

用matlab编写的雅克比方法求解线性方程组：数值分析中很经典的代码(a procedure of jacobi diedai)

说明：  FSK差分检波系统仿真的课程设计 本课程设计主要利用MATLAB集成环境下的Simulink仿真平台，设计一个FSK信号差分检波系统。观察FSK调制前后的信号波形,并对调制前后信号的频谱进行分析,再以调制信号为输入，构建差分检波解调系统电路，观察解调前后的信号波形，并对解调前后信号的频谱进行分析。加入噪声分析通过三种不同信道FSK信号差分检波系统接受信号的性能。仿真结果，基本达到课程设计要求。(FSK differential detection system simulation of the curriculum design of this course the main use of MATLAB integrated design environment of Simulink simulation platform, the design of a FSK signal differential detection system. Observed before and after FSK modulation signal waveforms, and modulation signal spectrum before and after analysis, and then modulated signal as input, build a system of differential detection demodulator circuits, observe the pre-and post-demodulation signal waveforms, and signal demodulation spectrum before and after analysis. Adding noise analysis through the three different channel FSK signal differential signal detection system to accept performance. The simulation results, the basic courses to meet the design requirements.)
