Linear Block Codes

Linear block codes are a method used in digital communication to detect and correct errors in transmitted data. They work by dividing data into fixed-size blocks and adding extra bits, called parity bits, calculated through algebraic rules. These added bits help the receiver verify the integrity of the data and fix any errors caused by noise or interference during transmission. Essentially, linear block codes enhance data reliability by transforming message blocks into codewords that can be checked and corrected, ensuring accurate communication over imperfect channels.
