此文档具体说明了如何设计二进制psk通信系统以及使用相关软件进行仿真(design of communication system)

说明：  用matlab中的FFT函数实现了正弦信号，矩形信号，和白噪声的频谱分析(FFT with matlab function in a sinusoidal signal, the rectangular signal, and white noise spectrum analysis)

用matlab实现基于LBGG算法的向量量化编码可直接使用。 (Using matlab to achieve vector quantization coding based on LBGG algorithms can be used directly.)

利用自然梯度算法，采用的是通用的平面波展开法,可以得到很精确的幅值、频率、相位估计。( Use of natural gradient algorithm, Using common plane wave expansion method, You can get a very accurate amplitude, frequency, phase estimation.)

该函数是常用于求解采样信号的起点的matlab函数(matlab function used for the start point of signal)

an image analysis set of codes to help you in understanding probabilistic image analysis for pattern recognition , machine learning and computer vision research works

说明：  典型的实验函数,可以用来测试算法的性能!(Typical experimental function, can be used to test algorithm performance!)
