ELE4606 Communication Systems

Semester 2, 2019 Online
Short Description: Communication Systems
Units : 1
Faculty or Section : Faculty of Health, Engineering and Sciences
School or Department : School of Mechanical and Electrical Engineering
Student contribution band : Band 2
ASCED code : 031307 - Communications Technologies
Grading basis : Graded


Examiner: Andrew Maxwell


Pre-requisite: (ELE2504 and ELE2601) or Students must be enrolled in one of the following Programs: GCEN or METC or MEPR or MENS or GCNS or GDNS

Other requisites

Recommended prior or concurrent study: ELE3506 and ELE4605


The purpose of this course is to provide an introduction to the specialised techniques and components which are common to both analog and digital communication systems. Topics studied include phase locked loops, noise, modulation methods, electromagnetic propagation, antennas and optical fibre communication. The relevance of these topics is illustrated by reference to existing communication systems such as the telephone network, TV, cellular mobile and microwave radio, radio navigation aids, and satellite communication systems. The course is intended for final year electrical degree students, and assumes some knowledge of electromagnetic fields and Maxwell's equations.


The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. demonstrate an awareness of standards such as CCIR and CCITT recommendations;
  2. calculate the performance of simple communications circuits;
  3. calculate the propagation characteristics of electromagnetic waves in free space and in the troposphere;
  4. analyse the performance of simple aerials and aerial arrays;
  5. analyse the structure and identify the relationship between various subsystems in modern communication systems.

  1. Student Administration will advise students of the dates of their examinations during the semester.

Important assessment information

  1. Attendance requirements:
    It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.

  2. Requirements for students to complete each assessment item satisfactorily:
    Requirements for students to complete each assessment item satisfactorily:
    To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the weighted marks available for that assessment item.

    Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.

    To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure (point 4.4.2).

  5. Method used to combine assessment results to attain final grade:
    The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.

  6. Examination information:
    In a Closed Examination, candidates are allowed to bring only writing and drawing instruments into the examination.

  7. Examination period when Deferred/Supplementary examinations will be held:
    Any Deferred or Supplementary examinations for this course will be held during the next examination period.

  8. University Student Policies:
    Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at

Assessment notes

  1. Students must familiarise themselves with the USQ Assessment Procedures (

  2. IEEE is the referencing system required in this course. Students should use IEEE style in their assignments to format details of the information sources they have cited in their work. For further information on this referencing style, refer to the below website:
