牛顿迭代法用于求解非线性方程组，及求解范围(Newton iterative method for solving nonlinear equations, and solve the range)

各种插值方法的效果比较 线性内插法，内插法，三次多项式内插法，多项式拟合法 将这些内插的结果及原先的采样点画在同一个图 (The effect of various interpolation methods compared linear interpolation, interpolation, cubic polynomial interpolation, polynomial fitting interpolation of these results and the original sample at the same Chart stipple)

ofdm系统性能的仿真，matlab版，可以直接运行()

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.)
