一些通信系统的仿真程序，包括简单的CDMA、FDMA和TDMA系统(Some communication system simulation program, including a simple CDMA, FDMA and TDMA systems)

频率切片小波变换程序（FTWT），matlab的m文件。从一种新的角度出发，通过自由选择频率切片函数、引进新尺度参数，在频率域实现小波变换，该变换能够很好地刻画信号各成分之间的相对能量关系。此外，频率切片小波变换的时频窗中心频率就是观测频率，而无需进行尺度换算。(Frequency slice wavelet transform procedures (FTWT), matlab m file. Starting from a new angle, through freely chosen frequency slice function, the introduction of a new scale parameter, the wavelet transform in the frequency domain, the transformation can portray the relative energy relations between the components of the signal. In addition, the frequency slice wavelet transform frequency is the observation of the time-frequency window center frequency without scale translation.)

说明：  该课题为基于MATLAB的数字水印系统。包括离散余弦DCT和小波变换DWT两种算法的对比，有一个GUI界面，包括嵌入，加噪，旋转，剪切，压缩等多种攻击，提取候，具有评价指标PSNR,NC等来评价算法的鲁棒性(This project is a digital watermarking system based on MATLAB. It includes the comparison of DCT and DWT. It has a GUI interface, including embedding, noise adding, rotation, cutting, compression and other attacks, extraction, and evaluation index PSNR, NC to evaluate the robustness of the algorithm)
