• Convolutional code — In telecommunication, a convolutional code is a type of error correcting code in which each m bit information symbol (each m bit string) to be encoded is transformed into an n bit symbol, where m/n is the code rate (n ≥ m) and the transformation… …   Wikipedia

• Concatenated error correction code — In coding theory, concatenated codes form a class of error correcting codes that are derived by combining an inner code and an outer code. They were conceived in 1966 by Dave Forney as a solution to the problem of finding a code that has both… …   Wikipedia
