matlab中几种常用的程序，对于熟悉matlab编程有很大帮助(some code in matlab，is useful for the new fish)

OFDM编码,调制的方法有QPSK,16QAM和64QAM(OFDM coding, modulation method QPSK, 16QAM and 64QAM)

人工编写的寻峰函数,可直接读取excel文件数据，并进行绘图。(the man-made function to find peaks.)

k均值聚类，有聚类数目，聚类中心，实现有效聚类。(k-means clustering, there is the number of clusters, cluster centers achieve effective clustering.)

这是用matlab编的代码，实现的功能是可以方便的给定一段信号，画出它的频域的频谱图，对写论文有帮助(This is compiled with the matlab code, function is convenient for a given period of the signal, draw its frequency spectrum chart, to help write the paper)

余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)
