Abstract
A soft decision decoding method which decodes a code having redundant bits added to information data bits and transmitted as an error correcting code and in which the received code is decoded bit by bit to produce a received word and reliability information for respective digits at which the received word and each of candidate code words disagree with each other is summed up. The receiving electric field level is detected for each digit of the received code, and the reliability information is obtained from the detected receiving electric field level.
