用泰勒级数展开的形式表示高动态的载波相位参数, 给出了对高动态载体和各阶频率参数 估计的四阶加权扩展卡尔漫滤波器(EKF) , 以及实现高动态跟踪滤波器必须的状态转移矩阵和动 态噪声协方差矩阵. 计算机模拟实验分析了对载波相位和各阶频率的跟踪结果.(Taylor series expansion with the form that the carrier phase high-dynamic parameters, given the high-order dynamic frequency carrier and the fourth-order parameter estimation Carl diffuse filter weighted extended (EKF), and to achieve the necessary high dynamic tracking filter state transition matrix and dynamic noise covariance matrix. The computer simulation analysis of carrier phase and frequency tracking results of each order.)

说明：  数据处理，FFT滤波求频率，曲线平滑；将时域信号去噪，再平滑，最后频域分析(Data processing, FFT filtering for frequency, curve smoothing)

this is the matlab ebook for digital signals and signal processing.......

this paper is about the image watermarking using DWT+DCT+CDMA. it provides a good PSNR value then each technique seprately
