Error correction of data transmitted in optical data transmission systems involves using serially chained, three-dimensional Single Parity Check turbo-code

摘要

The method involves generating a product code word, using an interleaver on the code word, generating a product code word from the code word from the interleaver, sending coded data over a transmission line, decoding the code word generated by the second encoder taking into account extrinsic information of a first decoder and decoding the code word generated by the first encoder taking into account extrinsic information of a second decoder. The method involves generating a three-dimensional Single Parity Check or SPC product code word with a first encoder (1), using an interleaver on the generated code word, generating a three-dimensional SPC product code word from the code word from the interleaver using a second encoder (2), sending coded data over a transmission line, decoding the code word generated by the second encoder with a second decoder (8) taking into account extrinsic information of a first decoder (7) and decoding the code word generated by the first encoder using the first decoder taking into account extrinsic information of the second decoder. AN Independent claim is also included for the following: an error correction system.
