EQ2831 Foundations in Digital Communications 7.5 credits

Teori för digital kommunikation

The course provides the theoretical background of the methods and principles used in modern digital communication systems. Detection and modulation theoretic aspects are the main focus, i.e., a comprehensive study of hypothesis testing, Gaussian stochastic processes, concept of sufficient statistics and matched filters, and parallelism to estimation theory. The emphasis is to provide a rigorous mathematical framework, optimization criteria, and models which are suitable for digital communication problems. Further, problem solving skills in related topics should be trained. The intention is to deepen existing knowledge on digital communication rather than to broaden.

Examination

  • INL1 - Homeworks, 7.5, grading scale: A, B, C, D, E, FX, F

Requirements for final grade

To pass the course the student

  1. has to hand in every homework. For each homework a minimum number of points must be achieved as well as the sum of all achieved points has to exceed a threshold, and
  2. has to sign up for presentation of at least one exercise solution for every homework set and has to present successfully at least one solution in one exercise seminar. Those who did not successfully present have to do a presentation of a selected paper.

The final grade for the course will be set according to the sum of all achieved points in the homework assignments. The levels will be fixed before the course starts.
