Objectives
This module builds on the first-year syllabus of 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.
Syllabus
Signals and Systems:
- Time domain representation of signals by functions; arithmetic with functions
- Analogue, digital, and discrete-time signals (functions)
- Periodic versus non-periodic signals (e.g., trigonometric signals, complex exponential functions)
- Frequency representation of analogue signals
- Fourier series for periodic signals
- Fourier transform for non-periodic signals
- Properties of Fourier transforms
- Revisiting bandwidth and spectrum
- Systems; Linear Systems; Time-invariant systems; LTI systems, e.g., filters; Transfer functions and impulse response functions; convolution
Communication Systems Theory:
- General structure of communication systems
Introduction to Digital Signal Processing
Sampling Theorem (detailed proof):
- Noise types and noise figure analysis;
- Data source compression (e.g., Huffman codes)
- Principles of error control block codes (e.g., Hamming codes)
- Baseband modulation techniques, e.g., pulse position/width/amplitude modulation schemes; amplitude carrier modulation schemes.
