用于DDS算法的验证

这是求分形关联维数的另一个ＭＡＴＬＡＢ程序，希望对大家有用(This is for the fractal correlation dimension, another MATLAB program, and they hope U.S. Useful)

说明：  fsk信号的调制与解调，通信领域其他各种调制方式可以参考此文件稍作修改(fsk signal modulation and demodulation, modulation communications can refer to various other minor modifications to this document)

分别使用矩形窗和汉明窗函数设计一个线性相位FIR低通滤波器，使其逼近理想低通滤波器的频率特性。采用频率抽样法设计FIR数字低通滤波器滤波器。(Using rectangular window and hamming window function to design a linear phase FIR low-pass filter, the frequency characteristics of the ideal low-pass filter. Frequency sampling method is used to design FIR digital filter based on low-pass filter.)

图像拼接，利用简易算法完成拼接过程，可实现不同数量的图像以为拼接。所采用图例为最新一届全国数学竞赛图片。绝对原创(Image mosaic, complete the splicing process using simple algorithm, which can realize image splicing different number of thought. The legend for the new session of the national mathematics contest. )

说明：  线性规划问题经典算法，matlab编写。(Linear programming problems classical algorithm, matlab prepared.)

这是关于数字水印的提取例程！经过调试，可以放心使用！(This is on the digital watermark extraction routines! After debugging, can be assured use!)

说明：  数字信号处理对于信号的基本matlab运算操作，有助于理解信号(The basic matlab operation of digital signal processing is helpful to understand the signal)

无线传感器有关能量协议的实现，跟其他现有邻居算法比较，性能上有很大的提高。(Wireless sensor realize agreement on the energy with the other existing neighbors algorithm comparison, the performance has greatly improved.)

这种方法一方面将像素的灰度值分散，可以分辨图象中比较细节的内容；另一方面，将图 象的灰度变化控制在一定范围之内，抑制了噪声的产生，较大程度上地保留了原始图象的亮度．(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)

MATLAB的小波变换在图象压缩中的应用，很适合初学者阅读。(MATLAB Wavelet transform in image compression, it is suitable for beginners to read.)
