说明：  mmse与snr的算法仿真，最小均方误差和最大信噪比，获得自适应算法的最优权，实现抗干扰(mmse snr algorithm and simulation, the minimum mean square error and maximum signal to noise ratio, the right of access to optimal adaptive algorithm to achieve anti-jamming)

说明：  用MATLAB编的边缘检测算子，包括Robert算子、sobel算子、prewitt算子。自己编写的，有利于初学者理解边缘检测算子的具体实现过程，将结果与MATLAB函数实现的结果作了比较。(MATLAB code with the edge detection operator, including the Robert operator, sobel operator, prewitt operator. I have written will help beginners to understand the specific edge detection operator implementation process to achieve the results with the results of MATLAB functions are compared.)

电力系统潮流计算程序，用于计算电网的功率流动。函数已写明所需参数，按照格式填写数据即可使用。(Power flow calculation program for calculating the power flow grid. Already indicate the required function parameters, you can use to fill in the data according to the format.)

数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 (Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.)
