DSTSTCOM DESIGN , USING CURRENT SOURCE CONVERTER IN MATLAB

Gantry detector tilt correction

It works as the IPToolbox s imadjust GUI Front End!

数字水印中，对于水印的置乱方法：Arnold置乱，通过改变像素点的位置增强水印的鲁棒性(Digital watermark, the watermark scrambling for ways: Arnold scrambling, by changing the position of pixels increase the robustness of the watermark)

基于压电传感器的振动测试探头的matlab模型(Based on piezoelectric vibration sensor test probe matlab model)

对二元序列10110010，画出2FSK的波形，其中载波频为码元速率的2倍。(For binary sequence 10110010, draw waveform 2FSK, where the carrier frequency of 2 times the symbol rate.)

多个体系统的集体行为是复杂系统研究的重要切入点, 而Vicsek 模型是 研究多个体系统的一个基本模型, 它具备了复杂系统的一些关键特征, 如动态行 为、局部相互作用和变化的邻居关系等.(Collective behavior of multi agent system is an important entry point for complex system research, and Vicsek model is a basic model of multi agent system, which has some key features of complex system, such as dynamic behavior, local interaction and changing neighbor relations)

这是一个在matlab下模拟ask 和 bpsk调制和解调的代码(this is a file wirtten by Matlab, to explain the ASK and BPSK in a correctly way )

采用数据拟合法进行的高斯白噪声信道下的信噪比估计，程序中有经典summer法以及本人自己拟合的二阶和三阶参数，适用于不同的信噪比范围，望大家一起交流(By data fitting of the Gauss white noise channel SNR estimation, the program in the classic summer method as well as my own fitting of the two order and three order parameters, applicable to different SNR range, hope everybody exchanges together)

The aim of this application is to implement scalable mpeg type compression by varying DCT coefficients and finding minimum number of DCT coefficients that can give minimum acceptable quality.. This application only works for gray scale.
