# APPLIED MATHEMATICS FOR COMMUNICATION SYSTEMS - 2021/2

Module code: EEEM062

## Module Overview

Expected prior / parallel learning**:** Knowledge of linear systems, linear algebra and stochastic processes is helpful, however, this is not a fundamental requirement. Students should have some background in arithmetic, complex numbers, integration and differentiation, and matrix calculations.

Module purpose: This module focuses on some of the fundamental mathematical concepts used in the analysis and design of modern digital communications systems and examines their application to link-level communications and receiver design.

## Assessment Strategy

The **assessment strategy** for this module is designed to allow students to show that they have achieved all the intended learning outcomes. The exam will assess their understanding on course’s material as well as their ability to apply the proper mathematical tools for solving analytical (numerical) and design problems. The exam will also assess their ability to perform simple design choices. In complement to the exam, the coursework assignment will test their abilities at modelling and evaluating the performance of simple digital communication systems.

Thus, the **summative assessment** for this module consists of the following.

- 2-hour, closed-book written examination at the end of the module teaching during the examination week
- Matlab IT lab based coursework assignment

**Formative assessment and feedback**

For the module, students will receive formative assessment/feedback in the following ways.

- During lectures, by question and answer sessions and through problem solving exercises
- During supervised IT lab, through discussion and supervision
- By providing feedback to unassessed tutorial problems
- Class discussion or electronic voting: Average 20 minutes every week during the lectures

## Module aims

- The aim of this module is to provide an introduction to some of the most fundamental mathematical concepts and tools used for the analysis and the design of digital communication systems as well as to provide an introduction to techniques and methodologies that are used in state-of-the-art digital receiver design.

## Learning outcomes

## Methods of Teaching / Learning

**The learning and teaching strategy** is designed to efficiently introduce the students to the concepts, methodologies and mathematical tools of the course and to provide them with pointers that can further use for deepening their learning experience. Lectures and practical lab sessions are the two main vehicles for delivering the strategy; lectures are designed to provide fundamental knowledge about the various topics of this module, whereas practical sessions are designed to support and further this knowledge via practical implementation in Matlab. The practical lab sessions are complemented by a coursework assignment. In order to increase the effectiveness of the provided feedback to and from the students, class discussions, problem solving and/or electronic voting are used; additional learning material is also added on SurreyLearn to address learning difficulties.

**Learning and teaching methods** include the following.

**Lectures**: 11 weeks – 23 hours ( 2 hour lecture per week x 10 weeks + 3 hour revision lecture)- Supervised IT labs: 10 weeks – 12.5 hours (1.5 hour lab per week x 5 weeks + 1 hour lab per week x 5 weeks)
- Self/guided study from the lectures and use of tutorial sheets.

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.
