6.02 Introduction to EECS II: Digital Communication Systems
6.02 Introduction to EECS II: Digital Communication Systems (Fall 2012, MIT OCW). Instructors: Prof. Hari Balakrishnan and Prof. George Verghese. An introduction to several fundamental ideas in electrical engineering and computer science, using digital communication systems as the vehicle. The three parts of the course - bits, signals, and packets - cover three corresponding layers of abstraction that form the basis of communication systems like the Internet.
The course teaches ideas that are useful in other parts of EECS: abstraction, probabilistic analysis, superposition, time and frequency-domain representations, system design principles and trade-offs, and centralized and distributed algorithms. The course emphasizes connections between theoretical concepts and practice using programming tasks and some experiments with real-world communication channels.

| Lecture 02 - Compression: Huffman and LZW |
This lecture covers examples of Huffman coding and limitations of coding. Lempel-Ziv-Welch is introduced as an adaptive variable-length code, and an example is done in lecture.
