Post-Shannon Information Theory
Identification Capacity
What: Exponential gain in communication efficiency in terms of possible messages
Why: Increase number of possible messages over channel of capacity C and codeword block length n
How: Paradigm shift from asking what message was sent to asking if message was sent
Semantic Communication
What: Transmit the meaning of a message (semantic level), instead of the pure message (technical level)
Why: Resource efficiency -> Reduce power consumption, bandwidth, and computational requirements
How: Develop a common knowledge base between TX and RX; extract and encode the desired semantics of the information
