用3中误差扩散滤波器实现误差扩散，分别是floyd stein, sierra, Stenenson滤波器(Error diffusion filter with a 3 to achieve error diffusion, respectively, floyd stein, sierra, Stenenson filter)

strategy pattern example(An example for using a simple Strategy Pattern)

理解快速傅里叶变换和反变换的好资料，是在MATLAB环境下联系的例子 (it is a good materials of understand the fast Fourier transform and inverse transform.)

这是一个方便的计算FFT的程序带坐标的fft变换(It s a program for fftrl,)

说明：  对与模糊C-均值聚类初始值进行调节，以便达到最优(the adjust of the initial degree of membership)

根据伪随机序列理论，由混合同余法产生均匀分布的随机数，进而根据中心极限定理来产生高斯噪声。 分析所产生的均匀分布和高斯分布随机信号的均值、方差、自相关等数字特征，估计其概率密度函数并进行分析，估计其功率谱密度并进行分析。说明该高斯噪声是否符合白噪声特性。 对该高斯噪声进行FIR低通滤波，估计输出低通型限带白噪声的功率谱、相关时间等，并结合白噪声通过线性系统相关理论来进行分析。 (According to the theory of pseudo-random sequence, a uniformly distributed random numbers by mixed congruential method to generate Gaussian noise, and then according to the central limit theorem. Produce a uniform distribution of the analysis and the mean of the Gaussian distribution random signals, variance, since the digital characteristics of the correlation, the probability density function is estimated and analyzed, it is estimated that its power spectral density, and analyzed. The Gaussian noise is in line with the characteristics of white noise. FIR low pass filter of the Gaussian noise, the estimated output of low-pass type band-limited white noise power spectrum, time, etc., combined with the white noise to be analyzed by linear system theory.)

说明：  用matlab编写的用于跳频技术的基于simulink环境的仿真程序(using Matlab prepared for the frequency-hopping technology based on Simulink environment simulation program)
