Prerequisites
Probability theoryIntended learning outcomes
After having taken this course, the student is expected to be able to
- Obtain a random model for a source, given data from the source.
- Analyze random sources and calculate theoretical limits for coding performance.
- Understand and explain the concept of codes.
- Understand and explain how the following coding methods work
- Huffman coding
- Golomb coding
- Arithmetic coding
- Lempel-Ziv coding
- Burrows-Wheeler's block transform
- Understand and explain how adaptive Huffman coding and adaptiv arithmetic coding works.
- Design different types of coders and calculate their coding performance, given random source models.
- Know where the coding methods are used in different standards.
- Implement different coding methods, test these on real data and report the results in writing.
Course content
The course deals with coding and data compression from an information theoretic perspective. Subjects:
- Random models for sources
- Source coding theory
- Entropy
- Huffman coding
- Arithmetic coding
- Lempel-Ziv coding
- Burrows-Wheeler's block transform
- Adaptive coding methods

Teaching and working methods
The course consists of lectures, lessons and laboratory work.
Examination
| LAB2 | Small computer project | 2 credits | U, G |
| TEN1 | A written exam | 4 credits | U, 3, 4, 5 |
During the project, the students implement a couple of the coding
methods that are taught in the course and test them on several kinds of real data. The students can choose to work alone or in groups of two.

About teaching and examination language
The teaching language is presented in the Overview tab for each course. The examination language relates to the teaching language as follows:
- If teaching language is “Swedish”, the course as a whole could be given in Swedish, or partly in English. Examination language is Swedish, but parts of the examination can be in English.
- If teaching language is “English”, the course as a whole is taught in English. Examination language is English.
- If teaching language is “Swedish/English”, the course as a whole will be taught in English if students without prior knowledge of the Swedish language participate. Examination language is Swedish or English depending on teaching language.
Other
The course is conducted in such a way that there are equal opportunities with regard to sex, transgender identity or expression, ethnicity, religion or other belief, disability, sexual orientation and age.
The planning and implementation of a course should correspond to the course syllabus. The course evaluation should therefore be conducted with the course syllabus as a starting point.
The course is campus-based at the location specified for the course, unless otherwise stated under “Teaching and working methods”. Please note, in a campus-based course occasional remote sessions could be included.
