LEARNING OUTCOMES OF THE COURSE UNIT
Knowledge and understanding
The main goal of this course is to provide students with the ability to
understand the foundations of modern digital communication systems and, in particular,
- the digital communication systems in the presence of channels with memory;
- the techniques for complexity reduction;
- the advanced technique for channel coding and decoding;
- the performance analysis techniques for these systems.
Applying knowledge and understanding
The abilities to apply the acquired knowledge and understanding result to be:
- the design and performance analysis of moder digital communication systems;
- the selection and design of proper coding systems for a given communication channel.
Detection and estimation theory

ASSESSMENT METHODS AND CRITERIA
Written and oral exams. It is required to pass the written exam to be admitted to the oral exam. The final mark will be the arithmetic mean of both marks. The written exam is about the design and analysis of a digital communication system, the oral exam on the theoretical aspects. Intermediate written exams will be considerated upon students' request.
Lectures and exercises (approximately with a ratio 80%-20%). For the latter, the teacher will solve on the blackboard the exercises assigned to the students one week in advance. In such a way, the students can try to solve them at home and will take advantage much more of the interaction with the lecturer, and can explain their work
