字典树的基本功能是用来查询某个单词（前缀）在所有单词中出现次数的一种数据结构，它的插入和查询复杂度都为O(len),Len为单词（前缀）长度，但是它的空间复杂度却非常高，如果字符集是26个字母，那每个节点的度就有26个，典型的以空间换时间结构。(The basic function of the dictionary tree data structure is used to query a number of times a word (prefix) appears in all the words, which insertion and query complexity are O (len), Len is a word (prefix) length, but its space complexity is very high, if the character set is 26 letters, and that the degree of each node will have 26, the typical structure of space for time.)

在双 馈 式 发电 机简 化 等 值电 路 的基 础 上 建 立了 风 电 场 的 确 定 性 潮 流 模 型， 建 立 了 风 力 发电 机 的 随 机 分 析 模 型， 并 在 这 二 者 的 基 础 上 运 用 基 于 半 不 变量法的随 机潮流 进行计算(On the basis of double-fed generators simplified equivalent circuit on the establishment of a deterministic trend model for wind farms, the establishment of a stochastic model of the wind turbine, and based on the use of stochastic trend in semi-invariant law on the basis of both calculation)

双十字阵矢量水听器阵的指向性研究，自己写的，试试看(double ten is written by me)

将图像分为16*16的分块进行计算,稀疏矩阵采用DCT矩阵，观测矩阵采用高斯随机矩阵，重构采用OMP算法,对256*256大小的8bit灰度lena图像进行仿真( )

DFT BASED PRECODING FOR ostbc

K-means MATLAB源程序，适用于聚类分析的代码(K-means MATLAB programe)

说明：  该实例包含很多MATLAB经典实用源程序(The classic example of MATLAB contains many practical source)

matlab编写的串口调试工具，数据接收部分采用中断方式，保证了实时的数据显示 。在获取端口部分采用了try catch 的方式，可以更加方便的选取端口。(this is a simple serial tool scripted by matlab. I used interrupt to ensure the instant display of received data.)

This tutorial is the next of before, you will learn a few of the basic functions of Matlab. First we will start working with basic mathematical functions, setting variables, and generating time series.

说明：  仿真FM系统的调制解调全过程，有相干解调，非相干解调，包括大小信噪比的分析，十分完整~包含程序以及仿真结果。都是自己完成的，还有写程序中的一些问题和心得，希望对大家有帮助(The whole process of simulation FM system modulation and demodulation, coherent demodulation, non-coherent demodulation analysis, including the size of the signal-to-noise ratio, very complete to contain the program as well as the simulation results. All their completion, as well as write programs in a number of issues and experiences, we hope to help)
