认知无线电中基于遗传算法的频谱分配的时间开销仿真实验

使用matlab对两幅图像进行匹配，效果很好，值得参考！(Using matlab to match two images of the good results, it is also useful!)

这是（213）viterbi译码算法，用于awgn，fgnm和jakes信道中(viterbi decode)

这是我们稳态课程上的大作业，要求对ZIP负荷和电动机负荷进行参数辨识，算法这里选用的是遗传算法。所参考的负荷模型见艾芊老师编著的《电力系统稳态分析》一书。(This is the homework of our course, which demands us to distinguish parameters of ZIP load & Motor load with GA.)

Matlab 有限元法计算分析程序编写 相信很多朋友都用到有限元,希望对大家有帮助(Matlab FEM analysis programmers believe that many of his friends have used finite element, We hope to help)

使用simulink建立一个脉冲信号发生器(Using a pulse generator simulink)

本matlab函数，利用混沌映射不可预测性，遍历性和敏感性，以它们的参数和初始值的优异特性的，实现一个图像加密算法。我们引入了一个新的二维logistics函数。与现有的混沌映射相比，它具有更广泛的范围内混乱，更好的遍历性，混沌性和relativelylow实施成本。为了研究及其应用，我们提出了一个之乱转换（CMT），以有效地改变图像的像素位置。结合2D-logistics与CMT，我们进一步实现图像加密算法。(In this matlab test,we use the chastic s excellent properties of unpredictability, ergodicity and sensitivity to their parameters and initial values, chaotic maps are widely used in security applications. In this paper, we introduce a new two-dimensional Sine Logistic modulation map (2D-SLMM) which is derived the Logistic and Sine maps. Compared with existing chaotic maps,it has the wider chaotic range, better ergodicity, hyperchaotic property and relativelylow implementation cost. To investigate its applications, we propose a chaotic magic trans-form (CMT) to efficiently change the image pixel positions. Combining 2D-SLMM with CMT, we further introduce a new image encryption algorithm. )

主要使图像进行灰度化处理，matlab的源代码，视同再进一步的预处理中应用(Gray image)
