By completing this subject, students should be able to formulate their own answers to the following questions: What are the bandwidth and channel resources required for a digital communications system? What are the system elements and the performance of analogue communication systems? How is the digital modulation type chosen in system design? How is a channel code type chosen in system design? What is the bit error rate performance of various digital modulation types? How is a link budget used in system design? How are carrier, clock, and frame synchronisation achieved? How can systems be designed for multiple access communications?
Topics include: random processes and power spectral density; introduction to digital transmission; review of applicable mathematical concepts; the MAP detector; the maximum likelihood detector; digital modulation techniques; bit error rate performance; link design and the link budget; channel bandwidth requirements; multiple access techniques; synchronisation techniques; and channel coding.
Assessment: Typically assessment in this subject involves a combination of assessment tasks and mid-semester and final examinations.
