利用PHD算法对函数的频率进行估计并画出图形(you can obtain frequency of the function by the PHD algorithm and get the figure)

脉冲编码调制是数字通信的编码方式之一。主要过程是将话音、图像等模拟信号每隔一定时间进行取样，使其离散化，同时将抽样值按分层单位四舍五入取整量化，同时将抽样值按一组二进制码来表示抽样脉冲的幅值。(PCM pulse code modulation is one of the encoding methods of digital communication. The main process is to voice, image and other analog signal at a certain time for sampling, the discretization, while the sampling values by the hierarchical units four to five homes in rounding quantization, while the sampling value indicates the sample pulse amplitude according to a set of binary code.)

说明：  文档用了STFT,CWT,GABOR,SPWVD 等方法对跳频信号的参数进行了估计(STFT, CWT, Gabor, spwvd and other time-frequency methods are used to estimate the parameters of FH signals)

利用小波进行图像压缩，使用的是一代小波对图像进行的压缩(image compress using wavelet)

说明：  OK算法的Matlab计算包，包含了验证和拟合的过程(OK computing package Matlab algorithms, including the process of validation and fitting)

一种新型的信道编码的仿真程序，在下一代无线通信中比较有用(a new channel coding of the simulation program in the next generation of wireless communications more useful)

说明：  随着电力系统运行环境的复杂化,系统运行状态的不确定性因素多元化,给电力系统分析带来了新的挑战。区间潮流因其建模简单等优点而成为不确定性潮流分析的主流方法之一。(Interval power flow program, which can be used to calculate interval power flow)

0.618法是根据黄金分割原理设计的,所以又称之为黄金分割法。 (0.618 method is based on the design principles of the golden section, it is also known golden section method. )

利用差分方法求解带状线的特性阻抗等信息，适合初学者(The use of finite difference method for solving the characteristic impedance stripline information, suitable for beginners)
