说明：  本文应用软件无线电思想对全数字接收机中的几个关键技术进行了研究，对其中的基本结构及基本模块进行了建模仿真。 (In this paper, thinking of all-digital software radio receiver in several key technologies were studied, of which the basic structure and the basic module of modeling and simulation.)

四元数更新在matlab中的实现，包括采样、更新四元数、规范化、得到姿态角(Quaternion update)

基于matlab的音频分组器设计，里面有详细代码，简单易懂(Matlab audio packet-based design, which has a detailed code, easy to understand)

说明：  交流微电网下垂控制simulink仿真 数据齐全 结果优秀(The simulation data of AC microgrid droop control simulink is complete and the results are excellent)

Conversion between absolute and relative path names

Here the syms toolbox is used and if you try to print any other values than lambda then MATLAB will print the value in fractions and that is unavoidable. So if you need to know the value in decimal, then use the command vpa() on command window

超声成像得到的射频信号转换为包络信号时的一维滤波(RF signals into ultrasound imaging to obtain one-dimensional filtering of the envelope signal when)

这是一维小波去噪程序 包括4种阈值和软硬阈值去噪，以及去噪后精度评定，方便大家一起学习(This is a one-dimensional wavelet denoising procedure Including four threshold and soft threshold denoising, and accuracy uation after denoising, facilitate everybody study together )

说明：  simple shoortest path
