经典leach ，仿真成功，是学习matlab仿真的最有效的代码(The classical leach, the simulation is successful, is to learn matlab simulation is the most effective code)

用自适应门限的方法进行跳频信号的参数估计，取得了较好的效果(Adaptive threshold method estimates the parameters of frequency hopping signals, achieved good results)

说明：  2维高斯拟合 实验过程中用到的 主要是对自己的实验数据的分布频数进行一个二维的高斯拟合来方便可视化实验数据的分布(In the process of 2-D Gaussian fitting experiment, we mainly use a 2-D Gaussian fitting for the distribution frequency of our experimental data to facilitate the visualization of the distribution of experimental data)

说明：  注水算法是根据某种准则，并根据信道状况对发送功率进行自适应分配，通常是信道状况好的时刻，多分配功率，信道差的时候，少分配功率，从而最大化传输速率。实现功率的“注水”分配，发送端必须知道CSI。(Water injection algorithm is to allocate transmission power adaptively according to certain criteria and channel conditions. Usually, when the channel is in good condition, more power is allocated, and when the channel is poor, less power is allocated, so as to maximize the transmission rate. To realize the "water injection" distribution of power, the sender must know CSI.)

对构件进行优化分析时，需要将其剖分成四面体网格单元，本源码可以用来求每一个小四面体的刚度矩阵(Optimization analysis of the components need to be partitioned into tetrahedral grid cell, the source can be used to seek the stiffness matrix of each small tetrahedron)

该模型是模拟信号数字传输系统，可以把一个模拟信号通过PCM编码译码，信道2FSK编码译码，再通过一个二进制对称信道，可以恢复出原模拟信号(The model is the analog signal digital transmission system, an analog signal by the PCM codec, channel 2FSK codec, and then through a binary symmetric channel, you can restore the original analog signal)
