在瑞利通道下，连续相位调制信号多用户检测(In the Rayleigh channel, the continuous phase modulated signal multi-user detection)

说明：  用6阶CIC实现，加噪声仿真。序内加详尽注释。(6 bands CIC realized, plus noise simulation. Sequence with a detailed note.)

matlabcontourlet变换结合了不可分离的方向滤波组,具备小波所不能表达的多方向特性,能有效捕获自然图像的边缘轮廓信息。本文分析了图像ontourlet系数的统计特征,并利用广义高斯函数对各子带系数层进行建模。将此模型应用于基于VisTex的自建纹理图像库,采用矩匹配估计法,提取模型参数集,运用K2L (matlab)

说明：  瑞利随机数的生成，通过两个同方差的正态分布而求得，并求出其PDF和CDF(Rayleigh random numbers generated by two normal distribution with variance that obtained and solved its PDF and CDF)
