长周期光栅的透射谱MATLAB模拟算法基于光栅的耦合理论。(Long-period grating transmission spectrum MATLAB simulation algorithm is based on the grating coupling theory.)

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

说明：  用matlab进行中值去噪的程序，建立一个被噪声污染的函数然后进行中值去噪处理。(Median denoising using matlab program, the establishment of a noise pollution function then median denoising.)

华氏温度(TF)、摄氏温度（TC）、开氏温度（TK）、兰金温度（TR）之间的换算(Fahrenheit (TF), Celsius temperature (TC), Kelvin temperature (TK), the translation between the Rankine temperature (TR))

这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)

说明：  可以用来检测心电信号R波的位置和个数，使用方便准确率高(It can be used to detect the position and number of R wave of ECG signal, and it is convenient to use and has high accuracy)

这是一个关于matlab下HP滤波器函数代码，非常好用(it is HP funtions used in matlab software)

用MATLAB在M文件里编写连续谱密度函数(matlab)

内部资料，很经典的MIMO和OFDM的课本程序，以供大家参考(it is important MIMO-OFDM program)

this is some script files and functions that introduce finite element method to start
