基于离散余弦变换（DCT）的数字水印源代码包括水印生成、嵌入、提取等(Based on the discrete cosine transform (DCT) of the digital watermark source code including the watermark generation, embedding, extraction, etc.)

两种中继增益选择蒙特卡洛仿真的比较,基于matlab语言(Two kinds of relay gain selection Monte Carlo simulation comparison, based on matlab language)

matlab非常重要的几点经验，非常值得留意和注意。(matlab a few very important experience, very worthy of attention and attention.)

 产生长度为1000的标准正太分布的随机信号，画出时域波形及频谱；  采用u=255的非均匀PCM编码，每符号为8bit，画输入-输出关系图；  计算信号量化噪声比（SQNR）；  信道误码率为10-3；  解码，并画出u律反变换后的信号时域波形及频谱。 扩展要求：  采用均匀PCM、量化级数可变、信道误码率可变。 ( have a standard length of 1000 is too random signal distribution, draw time-domain waveform and frequency spectrum  u = 255 using the non-uniform PCM encoding, each symbol for 8bit, drawing input- output relationship diagram  calculated quantization noise signal than (SQNR)  channel bit error rate of 10-3  decoder, and law to draw u the signal after the inverse transform time-domain waveform and frequency spectrum. Expansion of the requirements:  uniform PCM, quantization level variable, a variable channel bit error rate.)
