语音的端点检测 噪声可以自己加 使用阈值进行检测 能量的阈值跟据经验来进行决定(Speech endpoint detection noise can add to the threshold detection energy threshold according to experience to the decision)

说明：  求解参数估计的常用算法——EM，即期望最大化算法，用于代替样本量不完全时的极大似然估计算法。(Common algorithm for solving parameter estimation- EM, expectation maximization algorithm is used to replace the sample size is not completely at the maximum likelihood estimation algorithm.)

有限元的程序，好用的，做毕业设计可以做参考(Finite element program, easy to use, do graduate design reference can be done)

说明：  数字通信塔，用增量调制将模拟信号转换为离散的数字信号，在基带中采用Miller码编码，信道编码采用汉明码，调制方式采用PSK,通过AWGN信道传输。(A digital communication system，PCM encoding converts analog signals into discrete digital signal, uses Miller code coding in baseband and Hamming code in channel coding , then PSK modulation way )

ekf 何友的数据融合的关于ekf的例子的代码，自己写的，不够优化，有需要子函数的联系我(the code of ekf)

说明：  关于雷达建模的一本书中很详细的Matlab代码，第3章：连续波和脉冲雷达。(Matlab code about radar system simulation, chapter3: continuous wave and pulsed radar.)

Two photon absorption

布拉格光纤光栅受外界力、温度综合影响后反射谱的影响仿真研究( Fiber Bragg Grating by the external force, the combined effect of temperature after the Simulation of reflection spectra )

说明：  光纤光栅耦合模法数值模拟与仿真，滤波功能，时延(Fiber Bragg Grating coupled numerical simulation model and simulation, filtering, delay)
