We are aiming for an incremental return to campus in accordance with guidelines provided by NSW Health and the Australian Government. Until this time, learning activities and assessments will be planned and scheduled for online delivery where possible, and unit-specific details about face-to-face teaching will be provided on Canvas as the opportunities for face-to-face learning become clear.

Unit of study_

ELEC3505: Communications

This is an intermediate unit of study in telecommunications following on the general concepts studied in earlier units such as Signal and Systems and leading on to more advanced units such as Digital Communication Systems. Student will learn how to critically design and evaluate digital communication systems including the elements of a digital transmission system, understand the limitations of communications channels, different analog and digital modulation schemes and reasons to use digital techniques instead of analog, and the effect of noise and interference in performance of the digital communication systems. On completion of this unit, students will have sufficient knowledge of the physical channel of a telecommunications network to approach the study of higher layers of the network stack. The following topics are covered. Introduction to communications systems, random signals and stochastic process, components, signals and channels, sampling, quantization, pulse amplitude modulation (PAM), pulse code modulation (PCM), quantization noise, time division multiplexing, delta modulation. Digital communications: baseband signals, digital PAM, eye diagram, equalization, correlative coding, error probabilities in baseband digital transmission, bandpass transmission, digital amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK) and quadrature shift keying (QPSK), error probabilities in bandpass digital transmission, a case study of digital communication systems. Introduction to information theory: fundamental limits in communications, channel capacity and channel coding, signal compression.

At the completion of this unit, you should be able to:

  • LO1. work in a team, demonstrating capacity to manage complex roles and responsibilities, drawing on and optimizing the contribution of others towards the timely delivery of specific engineering tasks in a laboratory environment
  • LO2. design digital communication systems by applying principles and techniques developed in the material presented
  • LO3. demonstrate an understanding of the physical channel of telecommunications networks to the extent of the information presented throughout the course
  • LO4. demonstrate an understanding of the effect of noise and interference in the performance of digital communication systems
  • LO5. demonstrate an understanding of professional practice by differentiating between theory and real communication systems, identifying economic, social and sustainability standards employed
  • LO6. evaluate digital communication systems including the elements of a digital transmission system using knowledge of concepts, principles and techniques developed throughout the course
  • LO7. recognise the limitations of communications channels, as well as different analog and digital modulation schemes and explain the reasons to use digital techniques instead of analog.

Unit outlines

Unit outlines will be available 2 weeks before the first day of teaching for 1000-level and 5000-level units, or one week before the first day of teaching for all other units.

There are no unit outlines available online for previous years.
