For a source with entropy $H(X)$, the average codeword length $\barL$ of any uniquely decodable code must satisfy: $$\barL \ge H(X)$$
Finding a reliable PDF or comprehensive overview of can be a challenge for students and professionals. This subject forms the bedrock of modern digital communication, bridging the gap between raw data and efficient, reliable transmission.
The text typically follows a structured syllabus found in many technical universities (like VTU):
: These codes treat data as a stream rather than blocks. The Viterbi Algorithm is the standard for decoding these, often visualized through trellis diagrams. Syllabus and Chapter Breakdown
: Undergraduate and postgraduate students in Electronics and Communication Engineering (ECE). Length : 396 pages.
