Digital and Wireless Communications (Online)

Overview

This is a new online course aimed at teaching the core principles of digital and wireless communications along with methods of implementing these principles in practice.

The course will be delivered as a series of online live tutorials.

To augment the theoretical aspects of the course, various case studies will be discussed, and you will be able to apply the knowledge gleaned in the tutorials to work through structured software mini-projects based in MATLAB/Octave.

Taking this course will provide you with:

  • A comprehensive and rigorous treatment of modern digital and wireless communication techniques, viewed from a balanced perspective that illustrates how theory is applied in practice.
  • The knowledge to be able to critically appraise different techniques and to design/simulate fundamental aspects of communication systems.
  • A practical take on system modelling via software mini-projects, which will also be used to consolidate knowledge and to explore more advanced methods and theory.

The limited number of places available on this course ensures that everyone is able to take full advantage of the discussions and exercises.

Dates, Times and Delivery

The Digital and Wireless Communications (Online) course will run over online sessions delivered via Microsoft Teams on Tuesdays and Thursdays.

The live tutorials will be on Tuesdays and Thursdays from 12:00 - 15:30 (UK time) with a 30-minute break in between. The course is set to run on the following dates:

  • Tuesdays: 9, 16, 23, 30 November 2021
  • Thursdays: 11, 18, 25 November 2021

Access to the course VLE (virtual learning environment) will enable you to communicate with other students and view/download course materials.  Tutor support is available throughout.

A world clock, and time zone converter can be found here: https://bit.ly/3bSPu6D.

You should allow for 10 - 15 hours study time per week in addition to the weekly lessons.

Tutor

Prof Justin Coon

Course Tutor

Associate Professor in the Department of Engineering Science, Oxford University

Tutorial Fellow of Oriel College

Dr Coon has worked in the field of communications and networks for over 15 years. He spent a decade in industrial research labs (HP Labs and Toshiba Research Europe Ltd) before moving back to academia full time.

He is currently an Associate Professor in the Department of Engineering Science at Oxford University and a Tutorial Fellow of Oriel College where he teaches various courses and tutorials on mathematics, electricity and electronics, control, semiconductor physics, and communication theory and system design.

Dr Coon's research interests include communication techniques and analysis, network theory, random graphs, quantum networks and sensing, and error correction for storage and communication channels. His (reasonably) up-to-date CV can be found here.

Level and demands

The course is designed to appeal to graduate level engineers, physicists, mathematicians and computer scientists who have limited experience with and/or limited knowledge of communications.

This course is also an ideal refresher course for those who have previously studied communications.

Knowledge of and basic competence in mathematics (calculus, linear algebra, probability) will be helpful but is not absolutely essential; all basic theory will be covered through preparation material, extra reading, and during the first unit.  

 

IT requirements
