Module summary

The teaching and assessment methods shown below will be kept under review during 2021-22. In particular, if conditions allow for alternative formats of delivery, we may amend the timetable and schedule appropriate classes in addition to (or in place of) any online activities/sessions. Where learning activities are scheduled to take place on campus, it may be possible and/or necessary for some students to join these sessions remotely. Some of the listed contact hours may also be optional surgeries. Students will be provided with full information about the arrangements for all of these activities by the module staff at the beginning of the teaching semester.‘Independent online learning’ may involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or mini-projects, etc. Students will be expected to fully engage with all of these activities. The time commitment for independent online learning, and also the frequency and duration of online sessions are approximate and intended as a guide only. Further details will be confirmed when the module commences.Where assessments are shown as Online Time-Limited Assessments, the durations shown are indicative only. The actual time permitted for individual assessments will be confirmed prior to the assessments taking place.


This module gives students an introduction to various layers in modern communications networks and how the Internet works. It provides the student with skills to apply programming tools (MATLAB) to model communication signals and systems.

Learning outcomes
On completion of this module students should be able to:

1. Explain of the principles behind the organisation and operation of communications networks.
2. Describe the layered structure of communications networks and discuss the role of each layer.
3. Analyse and solve well-defined problems involving basic communications signals.
4. Use programming tools to model some of the basic signals, components and applications of communications systems.
5. Use simulations to identify the technical challenges in both the design and implementation of modern communications networks.


Topics may include, but are not limited to:

Part 1: Networking and the Internet

Data communications; sending bits around
Data communication networks; Internet
The use of layering, protocols, and interfaces
TCP/IP structure
Packet switched networks
Transmit control protocol
Network layer and Internet protocol
Data link layer and Physical layer
Application layer, e.g, email communications

Part 2: MATLAB Programming and Signals

Introduction to communications signals; Sine waves, frequency, phase, amplitude
Introduction to MATLAB programming; how variables are defined and manipulated
Representing important communication signals with MATLAB; sine waves, frequency, phase and amplitude; sum of harmonics
Basics of programming; if statements; for loops, with simple applications in communication networks
Modelling certain communication tasks, e.g., analogue to digital conversion by MATLAB
Modular programming; how to write and call functions and its application to communications protocols

Private study

Students are expected to use private study time to consolidate their understanding of course materials, to undertake preparatory work for seminars, workshops, tutorials, examples classes and practical classes, and also to prepare for in-course and summative assessments.

Opportunities for Formative Feedback

Students studying ELEC modules will receive formative feedback in a variety of ways, including the use of self-test quizzes on Minerva, practice questions/worked examples and (where appropriate) through verbal interaction with teaching staff and/or post-graduate demonstrators.
