The aim of this subject is to develop a thorough understanding of the main concepts, techniques and performance criteria used in the analysis and design of digital communication systems and wireless networks.
Such systems and networks lie at the heart of the information and communication technologies (ICT) that underpin modern society and are very much part of the Internet of Things which involves machine to machine communication.
This subject provides an in-depth treatment of the main concepts and techniques used in the analysis and design of digital communication systems and wireless networks.
- Source coding; entropy, Shannon source coding bound, data compression techniques;
- Channel modelling, modulation over time-varying fading channels, time and frequency diversity, energy and spectral efficiency, multiple carrier modulation including orthogonal frequency division multiplexing (OFDM) modulation, phase noise characteristics and its impact on single-carrier and multicarrier systems, spatial multiplexing for multiple access protocols, multiple antenna technologies (MIMO systems), cellular networks;
- Channel coding for error control: mutual information, channel capacity, Shannon channel coding bound, channel coding concepts, block codes; convolutional / trellis codes; introduction to LDPC codes, turbo codes, polar codes.
Examples include short, medium and long range communication systems such as bluetooth, cellular and satellite communication systems.
Intended learning outcomes
Students completing this subject will be able to:
- ILO 1 - Understand and model channel impairments such as noise, interference and fading;
- ILO 2 - Articulate what techniques can be used to communicate effectively despite channel impairments;
- ILO 3 - Describe the performance measures that are used to assess effective communication in digital communications systems and wireless networks;
- ILO 4 - Relate the overall performance of digital communications systems and wireless networks;
- ILO 5 - Develop systems engineering skills in translating transmitter/channel/receiver requirements and constraints into the specification of digital modulation and coding schemes;
- ILO 6 - Value the broader context, implications and applications of digital communication systems in society.
On completion of this subject, students will have developed the following skills:
- Ability to apply knowledge of basic science and engineering fundamentals;
- In-depth technical competence in at least one engineering discipline;
- Ability to undertake problem identification, formulation and solution;
- Ability to utilise a systems approach to design and operational performance;
- Capacity for independent critical thought, rational inquiry and self-directed learning;
- Ability to communicate effectively, with the engineering team and with the community at large.
