Brief Description

This is first trimester core unit out of a total of 24 units in the Bachelor of Engineering Technology (Telecommunications) BEngTech(Tel). This unit addresses the BEngTech(Tel) course learning outcomes and complement other courses in a related field by developing students’ specialised knowledge in digital comunications and applying critical skills in communication equipment such as Emona ET101 telecom trainer (Biskit). For further course information refer to:

Digital communication is one of the most commonly used modes of communication now a day, where organizations mostly rely on this mode for all their business communications. The main aim of this unit is to presents the principles and techniques fundamental to the analysis and design of digital communication systems.

Students will gain an understanding of digital communications systems. The unit focuses on the basic building blocks of a digital communication system (channel encoder/decoder, digital modulator/demodulator and channel characteristics). The emphasis is on practical experience in communications systems problem solving and experience in reporting laboratory experiments.

This unit will cover the following topics:

  • Communication System Model
  • Analog modulation
  • Source coding
  • Digital baseband transmission
  • Digital modulation and demodulation
  • Digital bandpass transmission
  • Equalisation
  • Orthogonal Frequency Division Multiplexing
  • Spread Spectrum systems
  • Digital transmission through wireless channels
  • Channel capacity and coding
  • Multiple Input Multiple Output systems
  • Multiple user communications

Learning Objectives

At the completion of this unit students will be able to:

  1. Demonstrate in depth knowledge of classification of analog and digital communication systems
  2. Apply the principles used in the generation, transmission and reception of digitally modulated signals
  3. Explain the need for sampling and analogue to digital conversion and source coding
  4. Compare and apply digital modulation and demodulation techniques, channel coding and decoding and their performance
  5. Compare multiple input and multiple output systems in modern digital communication systems
  6. Apply the concept of multiuser communication and resource sharing
  7. Simulate digital communication applications using Matlab and hardware devices

Extent covered

                               The standard  is covered by theory and practice, and addressed by assessed activities in which the students always play an active role, e.g. workshops, lab submissions, assignments, demonstrations, tests, examinations
 The standard is covered by theory or practice, and addressed by assessed activities in which the students mostly play an active role, e.g. discussions, reading, intepreting documents, tests, examinations
 The standard is discussed in theory or practice; it is addressed by assessed activities in which the students may play an active role, e.g. lectures and discussions, reading, interpretation, workshops, presentations
 The standard is presented as a side issue in theory or practice; it is not specifically assessed, but it is addressed by  activities such as lectures or tutorials
 The standard  is not considered, there is no theory or practice or activities associated with this standard
