Bemærkninger:
The course is conducted as a reading and discussion meeting with
the teachers. Assignments will be handed out to each student and
discussed every course meeting. The assignments will be based on
the books:
Principles of lightwave communications by G. Einarsson and
Phase-Modulated Optical Communication Systems by Keang-Po Ho. The
assignments will be chosen according to students' needs and
interests.
