ERROR CORRECTING CODING METHOD BASED ON CROSS-LAYER ERROR CORRECTION WITH LIKELIHOOD RATIO AND APPARATUS THEREOF

摘要

A data decoding method using an error correction method based on a log-likelihood ratio (LLR) is disclosed. The method includes decoding a transport block based on a first error correction code, calculating a log-likelihood ratio (LLR) for each symbol of the decoded data, when the CRC of the decoded data fails, transmitting information of a symbol determined as error based on the LLR and the decoded transport block to a higher layer, and decoding the information of the symbol determined as error and the transport block based on a second error correction code, in a higher layer.
