Some information is discarded to achieve higher compression, acceptable in multimedia (e.g., JPEG, MP3). B. Channel Coding (Error Control)
is the practical application of these principles, focusing on the design of explicit methods— codes —to achieve the theoretical limits set by information theory. 2. Core Concepts of Information Theory Information and Coding Theory
The goal is to ensure reliable transmission by adding that allows the receiver to detect and correct errors caused by noise. Some information is discarded to achieve higher compression,
Shannon proved that if the transmission rate ( ) is less than the capacity ( ), error-free communication is possible. 3. Branches of Coding Theory error-free communication is possible.
Information and Coding Theory represent the mathematical backbone of all modern digital systems, ensuring that data is both for storage and resilient against the noise of the physical world.
