摘要： For the coded data that was transmitted via a communication channel, a known code portion thereof that is a code portion corresponding to known data is detected. When the known code portion is not detected from the coded data, the coded data will be decoded. When the known code portion is detected from the coded data, at least a part thereof will be replaced with normal data, and the decoding will be performed on the coded data after the substitution.

摘要： The decoding apparatus includes an ACS unit to execute an add-compare-select operation on encoded received data, and an error detector to detect whether there is an error in decoded data calculated based on the executed add-compare-select operation, and if there is an error in the decoded data, the ACS unit additionally executes the add-compare-select operation on the received data.

摘要： A de-interleaver has a TTI frame buffer storing a TTI frame before de-interleaving, a P bit information table storing P bit information containing the size and added position of P bits to be added to the TTI frame before de-interleaving, and a permutation rule table storing permutation rules of de-interleaving. The de-interleaver performs de-interleaving on the data stored in the TTI frame buffer based on the P bit information stored in the P bit information table and the permutation rules stored in the permutation rule table.

摘要： A decoding method relative to this application improves an error correction performance without increasing a memory. The decoding method includes obtaining a first decoded result from a first decoding path being on a trellis diagram; determining whether the first decoded result is incorrect or not; creating a second decoding path when the first decoded result is incorrect; and obtaining a second decoded result from the second decoding path.
