DIGITAL SIGNAL PROCESSING ADVANCED PROGRAMS MATLAB WITH OUTPUTS

说明：  FSK信号的解调，采用最原始底层语言编辑各模块实现(FSK signal demodulation, adopt the most primitive language editing each module implements bottom )

对语音信号进行高通、低通、带通滤波器处理(voice lowpass highpass bandpass)

基于dct的伪随机序列的数字图像水印，算法较为简单，鲁棒性一般，不能很好地抵御噪声攻击(Dct pseudo-random sequence-based digital image watermarking algorithm is relatively simple and general robustness against noise attack can not)

视频水印，在每一帧视频帧上嵌入水印，不可见性良好(video waterMarking,embed the watermark on each frame of video,invisibility is mediocre)

完全适用于摄影测量解析相对和绝对定向的matlab程序文件(Absolute Orientation & Relative Orientation)

本代码为割线法求解非线性方程组。其调用格式为[r,m]=mulGXF1(F,x0,x1,eps) 其中，F:非线性方程组；x0初始解；x1：初始解；eps：解的精度；m：迭代步数。(The code for the secant method for solving nonlinear equations. Its call format [r, m] = mulGXF1 (F, x0, x1, eps) where, F: non-linear equations x0 initial solution x1: initial solution eps: solution accuracy m: the number of iterative steps.)

基于高频电磁散射的物理光学法用于计算散射目标的RCS (Based on high-frequency electromagnetic scattering of the physical optics method used to calculate the scattering target RCS)

说明：  滤波方法的通用，值得大家学习 还可以在此基础上改进(Universal filter, is worth learning can be improved on this basis)

说明：  AWGN信道下，fqpsk 调制的MAP检测 (under awgn channel,MAP demodulation for FQPSK modulation)
