Unit Overview


Students are introduced to communication systems in order to understand the fundamental aspects of both analogue and digital communications. This includes filtering, modulation and demodulation, source and channel coding, and information theory.

Semester 2UWA (Perth)Face to face

Students are able to (1) apply filtering of random signals in the design of communication systems in the presence of random noise; (2) carry out noise analysis for analogue communication systems (in particular, for AM and DSB-SC signals); (3) analyse and design digital communication systems over various channels (e.g. AWGN channel and ISI channel); (4) analyse various analog modulation schemes in terms of system performance (i.e. SNR) versus system bandwidth and power requirements; (5) carry out performance analysis (e.g. probability of symbol error) of digital communication systems (in particular, for ASK, BPSK and FSK signals); (6) apply the basics of information theory in digital communications, and explain the basics of source coding and channel coding using simple examples; and (7) work effectively in a team.


Indicative assessments in this unit are as follows: (1) laboratory reports; (2) class tests and assignment; and (3) a final examination. Further information is available in the unit outline.

Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
  • Contact hours provide an indication of the type and extent of in-class activities this unit may contain. The total amount of student work (including contact hours, assessment time, and self-study) will approximate 150 hours per 6 credit points.
