一个基于边信息嵌入的数字水印程序,经过本人的实验,已实现,供各位享用(A side information embedded based on digital watermarking process, after my experiments have been realized, for your enjoyment)

一种直接扩频序列的SIMULINK仿真模型 MATLAB6.5及以上环境可完美运行 发射部分和接受部分的频率图波形图均以给出(A direct sequence spread spectrum and above MATLAB6.5 SIMULINK simulation model of the environment can be run perfectly and accepted part of the transmitter frequency waveforms are given in Figure)

选择输入信号的参数，以及抽样因子，以及采样参数，对信号分别进行上抽样和下抽样，方便非均匀采样的进行。(Select the input signal parameters, and sampling factors, as well as sampling parameters, respectively, on the signal sampling and down sampling, to facilitate the conduct of non-uniform sampling.)

基于R-L模型的CT扫描和滤波反投影重建的程序实现(Based on CT scan and filter back projection reconstruction RL model program)

使用matlab simulink 编写的钟摆运动(use matlab simulink to do a clock move)

Description Applies ideal binary mask to noise corrupted speech signal. The processing takes place within an FFT based short-time spectral analysis-modification-synthesis framework. The ideal binary mask is computed from an oracle (true) signal-to-noise ratio (SNR) through thresholding with local SNR criterion. The routine returns synthesized enhanced speech, the ideal binary mask and the true instantaneous spectral SNR.

信号维数的估计，ldpc码的编解码实现，迭代自组织数据分析。( Signal dimension estimates, Codec ldpc code implementation Iterative self-organizing data analysis.)

UEL beam单元，作者不详（网上下载，若作者有异议可通知本人删除）(UEL beam element)

说明：  产生一个chirp信号，给出时域及频域特性。利用匹配滤波器进行滤波。如果有延时也能正确滤波。(Generate a chirp signal, given the time domain and frequency domain characteristics. Filtering using matched filter. If there is delay filter can correct.)

使用matlab对卡尔曼滤波算法模拟，结果精确可用(Use matlab on the Kalman filter algorithm simulation results available)
