 Repetition code

A binary repetition code represents one bit by repeating it a fixed number of times. Majority decoding corrects fewer than half as many bit flips as the block length.

Repetition code is a simple form of error correction used in coding theory to transmit data robustly over noisy communication channels. The fundamental idea of repetition code is to enhance the reliability of a single bit of information by transmitting it multiple times. ### Basic Concept: In a repetition code, a single bit of data (0 or 1) is repeated several times.
