Synopsis

The subject of digital communications involves the transmission of information in digital form from a source that generates the information to one or more destinations. This course extends the knowledge gained from ECS332 (Principles of Communications) and ECS315 (Probability and Random Processes). Basic principles that underlie the analysis and design of digital communication systems are covered. This semester, the main focus includes performance analysis (symbol error probability), optimal receivers, and limits (information theoretic quantities). These topics are challenging but the presented material are carefully selected to keep the difficulty level appropriate for undergraduate students.
