这是在Matlab中编的图像数字水印的嵌入和提取程序,所用变换为小波变换,并实行盲检测,对搞这方面的研究人员非常有用.(This is made in Matlab in image watermarking embedding and extraction procedures used transform for wavelet transform, and a blind detection, for engaging in research in this area very useful.)

This zip contains a simple paper of SPIHT generated streams run length encoded ... later i ll be posting the MATLAB source code also and also SPIHT with Arithmetic coding

说明：  演化算法经典教材 入门者必备 很好的 非常深(Teaching beginners classical evolutionary algorithm must be very deep well)

用matlab仿真通信系统基带信号，包含单极性，双极性编码。(Matlab simulation of communication systems using baseband signals, including unipolar, bipolar coding.)

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

比较matlab中ceil()、floor()、round()等的量化误差大小。并比较不同的量化位数的误差(Compare matlab in ceil (), floor (), round (), etc. quantization error size. And comparing different error of quantization bits)
