xinhaochuli ，matlab做的，信号导入。滤波。有注释(xinhaochuli, matlab do, signal import. Filtering. Annotated)

快速计算菲涅尔衍射光场，将菲涅尔衍射公式转换为快速傅里叶变换FFT，可以直接嵌入程序中使用，对菲涅尔计算全息很有用！(Fast calculation of Fresnel diffraction field, Fresnel diffraction formula will convert the fast Fourier transform FFT, can be directly embedded program using the Fresnel CGH is useful! ! !)

自适应滤波原理（国外教材）计算机作业的MATLAB程序，调试通过，有一定的参考价值。(Principles of Adaptive Filtering (foreign materials) MATLAB computer operating procedures, testing is passed, there is a certain reference value.)

this code explains the performance of BPSK and QPSK modulation techniques in terms of there bit error probability. this code plots the simulated bit error rate of bpsk and qpsk in terms of SNR. both modulation techniques are explained in RAYLEIGH fading channel.

This is the code of DEEC protocol of wireless sensor network. It is a matlab code

Implementation of a rule using a Groovy script.

简单的CMA算法,适合初学者来学习，自己编写的，望采纳。(simple CMA algorithm)

说明：  低循环疲劳试验数据的异方差回归处理。可以获得材料的疲劳参数(Low cycle fatigue test data, heteroscedastic regression treatment. Material fatigue parameters can be obtained)

输入经度、纬度和高度，计算任意近地面的重力场(Enter the longitude, latitude and altitude, calculation of arbitrary gravitational field near the ground)

This code is related to the course Digital Communications. It easily reproduces the error probability as a function of the SNR per bit for QPSK and 16-QAM systems using MATLAB
