Module summary
In order to pass this module, students must obtain a mark of at least 30% in the final examination, as well as obtaining an overall mark of at least 40% for the module.Objectives
This module builds on the first-year syllabus of ELEC1410 and ELEC1405 and ELEC1420 to give more quantitative/analytical tools for the design of modern communications systems, including Fourier analysis and signal processing, as well as the statistical treatment of signals.Learning outcomes
On completion of this module, students should be able to:
- understand the principles of the operation and application of a representative range of communications and broadcasting systems, including the underlying aspects of probability and statistics;
- demonstrate an ability to apply mathematical analysis to analogue and digital, and time and frequency domain signals and systems. This includes Fourier analysis, linear system descriptions in time and frequency, the convolution, sampling of lowpass and bandpass signals, baseband modulation schemes, noise analysis, data source coding and block error control coding;
- demonstrate a knowledge and understanding of the mathematical principles behind signal analysis and be able to apply mathematical methods and tools to the analysis and solution of communications problems;
- apply quantitative methods and relevant computer software tools (e.g. MATLAB) to problems in communication systems.
