What is linear block code in digital communication?

A linear block code is a type of error-correcting code used in digital communication to ensure data integrity during transmission. It encodes a fixed-length block of data into a larger block by adding redundancy, allowing the detection and correction of errors that may occur during transmission. The coding process is linear, meaning that the sum (XOR operation) of any two codeWords results in another valid codeWord. This property simplifies both encoding and decoding, making linear block codes efficient for reliable communication.
