In [[Digital data|digital]] [[telecommunications]], '''channel coding'''<ref>{{Cite journal |title=Comparison between Different Channel Coding Techniques for IEEE 802.11be within Factory Automation Scenarios |year=2021 |pmc=8587646 |last1=Fanari |first1=L. |last2=Iradier |first2=E. |last3=Bilbao |first3=I. |last4=Cabrera |first4=R. |last5=Montalban |first5=J. |last6=Angueira |first6=P. |journal=Sensors (Basel, Switzerland) |volume=21 |issue=21 |page=7209 |doi=10.3390/s21217209 |pmid=34770516 |bibcode=2021Senso..21.7209F |doi-access=free }}</ref> is a pre-transmission mapping applied to a [[Digital signal (signal processing)|digital signal]] or data file, usually designed to make error-correction (or at least [[Error-detecting code|error detection]]) possible.

Error correction is implemented by using more [[numerical digit|digit]]s ([[bit]]s in cases of binary channel) than the number strictly necessary for the samples and having the receiver compute the most likely valid message that could have resulted in the received one.

Types of '''channel coding''' include:
*[[Parity check]]s
*[[Hamming code]]
*[[Reed-Muller code]] 
*[[Reed-Solomon code]] 
*[[Turbo coding]]
