  Topic 1

  Course Rationale and Goals

  The course is planned as a senior-level ‘Technical Elective’ course. It assumes that the students have a background in signals and systems, frequency domain spectrum, probability and statistics.  The course presents the fundamentals of digital communication systems and evaluates the performance of digital signaling on physical channels.
