定义锁相环的工作模式：单载波为“1”、BPSK调制为“2”、QPSK调制为“3”(The definition of phase-locked loop mode of operation: single-carrier for the " 1" , BPSK modulation for the " 2" , QPSK modulation for the " 3" )

这个程序能清楚显示灰度图形的灰度直方图，并能进行平滑与滤波处理，方便程序员观察了解图像。(this procedure will clearly show that the gray-scale graphics histogram, and for smoothing and filtering. Observer allows programmers to understand images.)

模糊综合评判计算程序 模糊综合评判的过程：1、灰色关联分析，求权重（程序见Relation）；2、模糊聚类分析，划分等级（程序见F_class）；3、隶属度计算，求隶属函数（程序见Subjection和subject）；4、模糊综合评判，计算各单元等级（程序见F_judge）。(Fuzzy comprehensive evaluation matlab code The process of fuzzy comprehensive evaluation: 1. Grey relational analysis to get weight (see Relation for program); 2. Fuzzy clustering analysis to divide ranks (see F_class for program); 3. Membership degree calculation to get membership function (see Subjection and subject for program); 4. Fuzzy comprehensive evaluation to calculate each unit grade (see F_judge for program).)

这是MATLAB的统计工具箱的应用，数模培训的必要内容(This is the MATLAB statistical toolbox of applications, several essential elements in training mode)

A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".
