有关于Matlab实现的频谱分析一篇文章指导(about Spectrum Analyzer in Matlab)

dsp based codings and run the files using matlab. it is very usefull who are working with tms320lf24xx dsp processor

仿真了超宽带的PPM调制的发射链路，包含完整源码(Simulation of the PPM modulated UWB transmitter link, contains the full source code)

说明：  用matlab函数imhist()实现给定图像的直方图；函数histeq()实现直方图均衡化；对给定图像，各自指定直方图，进行直方图匹配，使图像增强。(Using matlab function imhist () to achieve a given image histogram function histeq () to achieve histogram equalization on a given image, each designated histogram, histogram matching, so that the image enhancement.)

8 band kp method calculate the valence band structure, using finite difference method

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)

关于IQ解调的一些matlab例程，觉得很好，对初学者很有帮助，就分享了。(About IQ demodulation some matlab routine, I feel very good, very helpful for beginners, it is shared.)

基于一个字嵌入水印0和1bit,原理是将图像转换到空间域后选择系数类嵌入水印，能抗打印扫描攻击(based on a word and embedding watermark 0 1bit, the principle is to convert the image into the spatial domain selection class watermarked coefficient, )

Probabilistic transient stability with monte carlo methods. *Note: copy the text in matlab and the run.

说明：  认知无线电中频谱感知技术的AM信号能量检测技术和周期平稳检测技术(Spectrum sensing in cognitive radio technologies AM signal energy detection and cyclostationary detection)
