In [[coding theory]], '''puncturing''' is the process of removing some of the [[Parity bit|parity bits]] after encoding with an [[error correction and detection|error-correction code]]. This has the same effect as encoding with an error-correction code with a higher rate, or less redundancy. However, with puncturing the same decoder can be used regardless of how many bits have been punctured, thus puncturing considerably increases the flexibility of the system without significantly increasing its complexity.
