Incoding theory,puncturing is the process of removing some of theparity bits after encoding with anerror-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.

A pre-defined pattern of puncturing is used in an encoder, in some cases. Then, the inverse operation, known as depuncturing, is implemented by the decoder.

Puncturing is used inUMTS during the rate matching process. It is also used inWi-Fi, Wi-SUN,GPRS,EDGE,DVB-T andDAB, as well as in theDRM Standards.

Puncturing is often used with theViterbi algorithm in coding systems.

DuringRadio Resource Control (RRC) Connection set procedure, during sending NBAP radio link setup message the uplink puncturing limit will send to NODE B, along with U/L spreading factor & U/L scrambling code.^[1]

Puncturing was introduced byGustave Solomon andJ. J. Stiffler in 1964.^[2][3]
