METHOD AND APPARATUS FOR DECODING CONCATENATED CODE

摘要

A method and an apparatus for decoding concatenated code are provided to improve a decoding speed of the concatenated code using a log likelihood ratio about the output of the plurality of decoders. A log likelihood ratio about the received concatenated code is calculated(S110). A fist decoding data is generated by performing a first decoding of the reception data based on the log likelihood ratio(S120). The second decoding data is generated by performing the second decoding of the first decoding data(S130). The iterative decoding is determined based on the second decoding data(S140). If the iterative decoding of the receiving data, the log likelihood ratio is updated based on the second decoding data(S150).
