CET700 Signal Space and Modulation

Course Provider

School of Electrical and Electronic Engineering (EEE)



Academic Unit



The objective of this course is to provide learners with a good understanding of the fundamental principles underlying digital communication systems, with emphasis on signal space and various modulation techniques. Common modulation schemes are studied and analyzed for comparison purposes. Topics covered will be beneficial to the subsequent modules in channel coding and multiple access. 

This course is part of:
- Graduate Certificate in Signal and Media Processing
- FlexiMasters  in Signal and Media Processing
- Graduate Certificate in Information and Telecommunication Engineering
FlexiMasters in Information and Telecommunication Engineering

On completion of the course, the learners should be able to:

1. Understand the elements of digital communication systems;
2. Process signals within different blocks in both time and frequency domains and;
3. Differentiate various modulation schemes for transmission over channels.

Communication Signals and Baseband Transmission

Review of Fourier techniques. Spectral density and autocorrelation. The sampling theorem and aliasing. Baseband systems. Signal space concept.  Maximum likelihood receiver structure and its error probability. The matched filter and correlator.

Digital Modulation/Demodulation

Digital modulations. ASK. FSK. PSK. QPSK. QAM. Error performance of coherent and non-coherent detection of digital modulation. Effects of  intersymbol interference.

For engineers who wish to upgrade their technical knowledge and skills in the area of digital signal processing, which can be  used in the Infocomm industry to aid in filtering and in analyzing any kind of signal.
