Introduction to EECS II: Digital Communication Systems
MIT OpenCourseWare offers this MIT 6.02 course, which builds a full digital communication system in three layered parts: bits, signals, and packets. Students learn source coding and compression, error correction and channel coding, modulation and the time and frequency domain tools used to analyze signals, and packet-based networking including medium access and routing algorithms. The material connects abstraction, probabilistic analysis, and system design trade-offs to real engineering problems, with programming assignments and experiments run on actual communication channels rather than only simulations. Lecture notes, problem sets, exams, and lab materials are included, reflecting MIT's undergraduate EECS curriculum. The course is free to audit through MIT OpenCourseWare, with no certificate offered. It suits learners with some background in signals, probability, or introductory programming who want a grounded, hands-on view of how the Internet's lower layers actually work.
