Unit code: MATH32032
Credit Rating: 10
Unit level: Level 3
Teaching period(s): Semester 2
Offered by School of Mathematics
Available as a free choice unit?: N




To introduce students to a subject of convincing practical relevance that relies heavily on results and techniques from Pure Mathematics.


Coding theory plays a crucial role in the transmission of information. Due to the effect of noise and interference, the received message may differ somewhat from the original message which is transmitted. The main goal of Coding Theory is the study of techniques which permit the detection of errors and which, if necessary, provide methods to reconstruct the original message. The subject involves some elegant algebra and has become an important tool in banking and commerce.

Learning outcomes

On successful completion of this course unit students will

  • have a theoretical understanding of how methods of linear and polynomial algebra are applied in design of error correcting codes,
  • and be able to analyse and compare error detecting/correcting facilities of simple linear and cyclic codes for the symmetric binary channel;
  • be able to design simple cyclic codes with given properties.
