[CSIE 5521] Wireless Networking: Fundamentals and Applications

[CSIE 5521] 


Wireless Networking:

Fundamentals and Applications

Michael Tsai (蔡欣穆) 2017 Fall

Course objective

• Learn fundamentals


wireless communications and networking concepts:

• with a CS perspective

• straightforward (simple) math

• can we code to learn?

• get deep understanding from implementing and experimenting (real wireless channel)

Course objective

• Examples:

• How to represent digital bits with analog waveforms?

• How will the environment change the transmitted waveform?

• How to recover the transmitted digital information?

Course objective

• Touch upon some example wireless technologies

• WiFi

• Visible light

communications

• Vehicular networks

• Wireless positioning

Course Syllabus

• Basics

• Harmonic signal

• Complex exponentials

• Multiplexing

• Fourier transform

• Modulation

• WiFi and OFDM

• MIMO

• Spread spectrum and diversity

• VLC

• Positioning

• Vehicular Networks Note:

• More emphasis on physical layer

• NOT covering cellular technology

Fundamentals Applications

New elements in this edition

• Flipped classroom (when I can)

• More class activities + less lectures (mostly online)

• Coding to learn wireless (Matlab)

• Small experiments (deal with real channels)

• Improve learning performance (instead of just sitting there)
 (i.e., free up your time)

Experiment 


with teaching tools

• New “NTU Classroom” platform

• https://courses.dlc.ntu.edu.tw/

• Host online video and PDF notes + 
 some exercises

• Zuvio or slido: improve class interaction 
 (not yet set up)

• Maybe others.

Prerequisites

• You need to know programming (C, python, java, … anything)
 (but not necessarily Matlab)

• You need to know how to find answers 


“from Google”

• For example, how to get Matlab up and running

• Basic understanding of Calculus and probability

• Nice to have:

• You have taken “Computer Networks”

• You have taken “Data Structure” and/or “Algorithm”

“Class meeting” time

• Classroom: will switch from R102 to R204

• Flipped classroom:

• You NEED to watch all videos
 before coming to the class 


(announced in the previous week)

• Up to 2 hours of class activities (13:20-15:20)
 (discussion + lab)

• Regular lecture (backup plan)

• Up to 3 hours of class lecture + activities

Course grade

• Class interaction and participation (10%)

• Individual

• In-class exercises (tentatively, 8 x 5% = 40%)

• Two-person team

• Labs (2x10% = 20%)

• Two-person team

• Final project (30%, proposal, presentation, demo)

• Four-person team

Description of 


a few lab assignments

In-class Lab 3: JJY Simulator

• What is JJY?

• the call sign of a longwave time signal radio station

• What is the purpose of using JJY?

• Used to synchronize consumer radio-controlled clocks throughout Japan with Japan Standard Time(JST)

• In Japan, the station broadcasts the JJY signal from two sites

• The Mount Otakadoya : 40 kHz signal

• The Mount Hagane : 60 kHz signal

• Official website

Matlab

• A programming language developed by MathWorks

• Originally designed to process MATrix -> now a full-blown tool for general scientific computing

• A tutorial:

• Please install your own copy of Matlab (合法!):

• https://wslab.csie.ntu.edu.tw/2017/08/matlab-r2017a- installation-tutorial/

Reference books

Chandra, Dobkin, Bensky, Lexa, Lide, and Dowla, “Wireless Networking – know it all,”

Zero-tolerance policy (Plagiarism)

• We will NOT tolerate any PLAGIARISM (Quiz/Lab/Homework).

• Students who gets caught will get an

F

• The TA’s will look for

• (1) signs of copied codes in your project assignment source codes

• (2) signs that content in your final project is found somewhere else

• Please indicate references for each problem

• Books or Internet URL or a person.

• If none, then indicate “none”.

Zero-tolerance policy (assignment deadline)

• Homework deadline is HARD deadline.

• You get

0

• You get

0

submit the source code to the repository

• However, we will still grade it for you, if you choose to submit it (after the deadline)
