matlab的各种程序 适合初学者参考学习交流(matlab code)

Atoll 2.8.3 Technical Reference Guide

As we know, the energy needed for sensors should be electrical. So the rst step before start to work is to convert environmental energy to electrical one. Inside the node there are dierent components for sensing the area, collecting data and processing the data. So the main dierent part of this kind of nodes, in compare of WSN nodes, is the power part. Once the stored energy reach to a certain amount, the power supply for micro controller and transceiver will start to work. They will continue to work until they have energy, as soon as the energy nish, they stops and energy storage device start to work to save energy again. The other fact should be consider about EH-WSN node is that the available energy can change in dierent nodes. So every node has its own harvesting rate.

QAM仿真 实现星座调制 主要用matlab语言实现的(QAM simulation)

一本介绍卡尔曼滤波的基础书籍，其中包含大量的具体应用。(An introduction book for Kalman Filter)

在移动通信中的多路径信号接收机。环境的干扰，根据其相位使信号增加或减少。这个程序可以让你学到的频率和速度如何修改信号模式的接收器(In mobile communications a multi-path signal is received in the receptor. Enviroment interferences make the signal increase or decrease according to its phase. This program allows you to learn how frequency and speed modify the signal pattern at the receiver)

利用matlab来模拟正弦相位光栅，里面附有图说明(matlab simulation of sinusoidal phase grating)

• Assume you are a R/D manager of a communication equipment company, you are going to develop an IP Switch (including hardware and hardware), how do you arrange this project? (hint: what is the system architecture?Which technologies you need? How do you arrange your team into co-work groups?)

此段代买可以用来实现层次分析法，通过输入参数、更改参数，利用循环自动检验是否符合层次分析法的要求(solve the AHP problem)
