Learning Outcomes

At the end of this module, the student will be able to: 1. Perform source coding on a stationary data source with known statistics using Huffman coding, Shannon coding, arithmetic coding. 2. Calculate the entropy (self, mutual, conditional) of a random variable and interpret the result in terms of information content and theoretical limits to source coding performance. 3. Perform data compression of a stationary data source with unknown statistics. 4. Calculate the channel capacity of simple noisy channels including the binary symmetric case, and interpret the result in terms of theoretical limits to channel coding performance. 5. Design linear block codes (including Hamming and cyclic) and determine the error correcting capability of such codes. 6. Implement syndrome decoding for block codes. 7. Implement simple convolutional codes using state transition and trellis diagrams.

To give an introduction to source and channel coding. To develop the basic information theory to underpin these topics.

Assessment Criteria Semester Examination Assignments (2) Quiz

70% 20% 10%

Penalties: Late submission of assignments will be subject to a penalty of 10% of the assessment grade for each day (or part thereof) overdue. Pass Standard and any Special Requirements for Passing Modules: Pass 40% - students are not required to pass the written and continuous components separately - an overall pass mark of 40% is acceptable. Requirements for Autumn Supplemental Examination: The continuous assessment mark is carried forward to the Autumn examinations as there is no facility available for repeating the continuous assessment components of the course. Continual Assessment Results: Assignments will be corrected within two weeks, where that does not extend past the end of the semester. Results and corrected assignments will be available for viewing upon request. Assessment Philosophy Information Theory is a fundamental subject in communications and computer engineering. It requires a strong understanding of probabilistic and algebraic concepts and their applications in the setting of data compression and transmission. Weekly tutorials/labs are designed to reinforce material presented in lectures and will provide an informal assessment of the student’s grasp of all learning outcomes as the module progresses. There are two formal assignments given throughout the semester; these require the student to read around the core material of the lectures and will explicitly test learning outcomes 1-2 (Assignment 1) and outcomes 3-5 (Assignment 2). The class quiz assesses all learning outcomes with particular emphasis on outcomes 5-7. The final examination assesses all outcomes. Course Text
