SinWmk
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.)

Gold_Sequence_Generator
美国国家航空和宇宙航空局(NASA)研制的跟踪和数据中继卫星系统(TDRSS)的正交信号发生器使用的是阶数为r=11的GOLD序列,序列长为2047,m序列优选对为4445和4005,利用Matlab程序构造出这个序列,并且验证信号的平衡标准,PACF(离散周期自相关函数)和PCCF(离散周期互相关函数)。通过Matlab2009A测试。(NASA developed tracking and data relay satellite system (TDRSS) use of orthogonal signal generator is the order of the GOLD for the r = 11 sequence of length 2047, m sequence pairs for the 4445 and 4005, use of Matlab program to construct the sequence, and verify the balance of the signal standard, PACF and PCCF. Testing by Matlab2009A.)
