Digital Communications (H6106Z)
Digital Communications
Module H6106Z
Module details for 2021/22.
30 credits
FHEQ Level 6
Module Outline
This module introduces the basic principles of digital communications and applications. Digital communication is the pillar of the digital age and lies at the heart of modern society. It allows different type of information-bearing signals such as voice, images, video, as well as data to be communicated digitally over wires or the air. Mobile phones, WiFi, Internet, Bluetooth, and Digital TV are all examples of digital communication systems that we all use every day.
The module starts with an introduction to digital communication systems, signal and spectra, digitisation process and source coding for analogue signals. This is then followed by major topics on digital baseband and digital bandpass transmission and reception techniques used for wired and wireless communications. It finishes with higher level topics related to multiplexing, performance analysis, and information theoretic concepts.
The module is delivered by a series of lectures, exercise classes solving real problem and laboratory based project work using MALTAB software package. The module provides the student with fundamental knowledge and skills important in the design and analysis of digital communication systems. Graduates are expected to be employed by wide range of industry including telecommunication companies and other related industry.
Module Topics
The following topics will be covered in the module
· An introduction to communications systems, digital versus and analogue, main components and categories of
digital communication systems, and signals and spectra.
· Sampling and quantisation, pulse code modulation and differential PCM.
· Digital baseband transmission including data transmission fundamentals, line coding, binary and multilevel
signalling, pulse shaping, inter-symbol interference, noise in communication systems, and detection of digital signals.
· Digital modulation and demodulation techniques for wireless communications.
· Multiplexing methods.
· Error performance and bandwidth efficiency analysis.
· Fundamentals of information theory and coding.

Please note that the University will use all reasonable endeavours to deliver courses and modules in accordance with the descriptions set out here. However, the University keeps its courses and modules under review with the aim of enhancing quality. Some changes may therefore be made to the form or content of courses or modules shown as part of the normal process of curriculum management.
The University reserves the right to make changes to the contents or methods of delivery of, or to discontinue, merge or combine modules, if such action is reasonably considered necessary by the University. If there are not sufficient student numbers to make a module viable, the University reserves the right to cancel such a module. If the University withdraws or discontinues a module, it will use its reasonable endeavours to provide a suitable alternative module.
