一个关于混沌序列的噪声压缩程序，主要基于主分量分析方法，消噪效果非常好。模拟信号上加了100 ％噪声(a chaotic sequence of the noise compression procedures, mainly based on principal component analysis, denoising very good results. Analog signals on the 100% increase in noise)

说明：  加性高斯白噪声下，FQPSK调制的常规OQPSK检测(awgn channel, convention OQPSK demodulationfor FQPSK modulationfor)

以网格作为逻辑结构，具有高联通，低负载，扩展性强的特点。经分析表明，该方案更高效、安全、抗攻击能力更强。(To the grid as a logical structure, with high Unicom, low load, expansion and strong features. The analysis shows that the program more efficient, safe, stronger anti-attack capability.)

一个QAM的通信系统仿真，带时域均衡，误码率统计(a communications system simulation, with time domain equalization, error rate statistics)

说明：  基于小波系数块能量分析的自适应数字水印算法(Energy analysis based on wavelet coefficients of adaptive digital watermarking algorithm)
