This was used at the 2004 Cyber Summer Camp This program hides a message image in the lower bit planes of a cover image

its of signal and system in matlab.

向下延拓是不稳定算法，这个程序采用迭代法向下延拓，稳定性更好，自己编写的，供大家参考(Downward continuation algorithm is unstable, this program uses an iterative method for downward continuation, better stability, I have written for your reference)

说明：  雷达信号处理部分，包括正交相干检波、脉冲压缩、多普勒处理和恒虚警检测。(Radar signal processing parts, including the quadrature coherent detection, pulse compression, Doppler processing and CFAR detection.)

基于Matlab开发环境的数值计算英文原版书(Numerical Computing with Matlab- Cleve Moler (SIAM 2005 367 pg s))

本文的秘密编码离理想的码率还很远，建立的无 条件秘密通信系统的稳定性和秘密性有待进一步证明，无条件安全系统秘密编码 方案还处于起步研究阶段，还有很多新的突破点等待研究。(Stability and secrecy of the secret coding bit rate still far from the ideal, the establishment of the unconditional secret communication system needs to be further proof, the the unconditional security system secret coding scheme is still at an early research stage, there are a lot of new breakthrough wait for research .)

一个数学模型的优化 function testcon() ％％ 设置初始值，上下限； x0=[18 13 11] lb=[3 0.1 7] ub=[25 1 25] ％％ 调用优化求解函数(testcon) (Optimization of a mathematical model function testcon () set the initial value, the upper and lower limits x0 = [18 13 11] lb = [3 0.1 7] ub = [25 1 25] Call for Function Optimization (testcon))

使用matlab实现的很好用的，正确的直方图均衡化代码， matlab编写的(Using matlab to achieve good use, right histogram equalization code, matlab prepared)

详细给出了8dpsk系统的 误码率计算的matlab程序 并绘出了其误码率曲线(detailed 8dpsk given the BER calculation of Matlab procedures and draws its error rate curve)
