DECODER FOR PERFORMING ERROR CORRECTION DECODING BY REPEATED DECODING METHOD

摘要

A decoder (5) subjects encoded data (Xn) transferred to a communication path to an error correction decoding so as to obtain decoded data. The decoder (5) includes: a decoding processing unit (7) for performing an error correction decoding on the encoded data (Xn) by the repeated decoding method which repeatedly performs decoding operation; and a number-of-times deciding unit (12) which decides the number of repetitions of the decoding operation in accordance with the transmission characteristic of the communication path.
