ADVANCED SIGNAL PROCESSING - 2020/1

Module Overview

Expected prior learning:  Knowledge of the basic principles of matrices and vectors; probability and statistics; and digital signal processing (Fourier Transforms, LTI Systems, Z-Transforms). MEng students might have acquired this by study of modules EEE2035 Engineering Mathematics III and EEE3008 Fundamentals of Digital Signal Processing. MSc students might have acquired this by study of a module in engineering mathematics, and module EEE3008 Fundamentals of Digital Signal Processing or similar.

Module purpose:  Advanced signal processing, which includes adaptive filtering, signal detection, matching and recognition, is a key expertise required for designing and building high-tech. electronic systems such as robots, automatic speech recognition systems, driver warning systems, biometrics technology, etc. The module will introduce students to advanced techniques of signal processing and interpretation.

Assessment pattern

Alternative Assessment

Not applicable: students failing a unit of assessment resit the assessment in its original format.

Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The written examination will assess the knowledge and assimilation of the terminology, concepts and theory of statistical and adaptive signal processing, as well as the ability to analyse problems and apply mathematical models of signal processing to solve and predict effects. The Assignment will assess the ability to design pattern recognition systems. The laboratory experiment will evaluate the acquired technical skills and expertise required for performance characterisation of pattern recognition systems.
Thus, the summative assessment for this module consists of the following.

2-hour, closed-book written examination;

Pattern recognition assignment and experiment: An assignment and experiment involving the design and evaluation of pattern classification systems;

Formative assessment and feedback 

The main mechanism for formative assessment will be a set of tutorial problem sheets which the students will be expected to solve prior to the timetabled tutorial classes. The tutorial classes will provide the main forum for formative feedback. In addition, formative assessment and feedback may occur:

During lectures, by question and answer sessions;

During tutorials/tutorial classes;

During supervised laboratory sessions;

During meetings with lecturers and tutor.

Module aims

• Equip students with advanced analytical tools for solving the statistical and adaptive signal processing problems encountered in communications, telematics, and related engineering areas; and
• To introduce students to statistical and adaptive techniques for the detection, filtering and matching of signals in noise;
• Make students aware of the industrial relevance of these techniques.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to achieve the specified learning outcomes by teaching the module syllabus in lectures, and supporting the assimilation and understanding of the taught material via tutorial classes. The practical design and technical skills related to the subject are acquired through coursework involving an assignment on pattern recognition system design; the performance of the designed pattern recognition system is characterised via laboratory experiments.

Learning and teaching methods include:

Lectures: 10 weeks, 2-3 hours per week

Tutorials: 6-8 weeks, 1 hour per week

Revision classes: 2-3 hours

Assignment and Lab: Pattern recognition system design assignment and pattern recognition experiment

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
