Abstract
In an error control device, an error correction decoding portion 33 selects a bit position which has low reliability from the received signal by means of a predetermined bit number, generates error patterns by assuming that the errors exist at the bit position, and carries out modified Chase decoding for the received signals on the basis of each error pattern in modified Chase decoding portion 332. Modified Chase decoding portion 332 calculates the reliability of each error pattern by using the reliability of each bit in the received signal.
