将混合有白噪声的两个信号的频率提取出来，适合初学matlab的使用(Will be mixed with white noise, the frequency of two signals is extracted, the use of matlab for beginners)

Calculate the histogram and the entropy of any image. The entropy is calculated using different methods.

衰减记忆滤波算法,通过对原信号的滤波从而得到一阶、二阶信号导数的估计值(fading memory filter)

OFDM系统中基于DFT的信道估计技术仿真(OFDM system channel estimation based on DFT)

又一个很好的MATLAB应用范例。是关于MATLAB在upf领域的应用问题。(a very import tings!)

全向阵元和有向阵元的模式空间图，有助力于理解宽带波束形成(the mode pattern of ominidirectional array elements and directional array, it is helpful to understand the broadband beamforming)

Fresnel函数计算相对折射率所面临的问题是计算量较大，利用实测数据计算散射系数并作图显示结果(Fresnel function by calculating the relative refractive index is a calculation of the problems faced by large, using the measured scattering coefficient data and mapping the result will be displayed)

msk调制，以前作业时编的，很基本的东西，貌似还有dpsk(msk modulation operation for the past, and very basic things, looks like there dpsk)

kmin clustering is very good
