Objectives and Content

What is information? The course deals with measures of information content of digital symbols and sequences of symbols. Based on Shannon's information theoretical framework, an introduction to the fundamental principles behind data compression, error-correcting codes, and cryptography is given. In the course we also consider how information theory can be applied to computer networks, and we study information-theoretic wiretap channels in order to introduce the connection between security and information theory. We also investigate applications to gambling and horse betting.

Learning Outcomes


The student should be able to:

  • Explain the concepts of entropy and mutual information.
  • Understand how information can be represented in an efficient manner.
  • Explain how information theory can be applied to multiple-access channels, broadcast channels, and to general networks.
  • Explain information-theoretic aspects of information security.


The student should be able to:

  • Determine the channel capacity of a discrete memoryless point-to-point channel with given parameters.
  • Implement source coding algorithms for simple sources and sources with memory, and other algorithms covered by the course.

General competence

The student

  • has a good understanding of the field of information theory.

Required Previous Knowledge

For incoming exchange students: At least 60 ECTS in Computer Science and at least 10 ECTS in mathematics

Recommended Previous Knowledge
