CONTINUOUS CODE DECODER AND DECODING METHOD FOR RECIRCULATING PARITY BIT

摘要

PURPOSE: A continuous code decoder and decoding method for recirculating a parity bit are provided to stably decode data even in a noisy environment. CONSTITUTION: A continuous code decoder includes the first inner decoder(302), the first outer decoder(312), the second inner decoder(320) and the second outer decoder(328). The first inner decoder receives and decodes data representing continuous code and outputs the first inner message data and a parity data. The first outer decoder decodes the first inner message data and outputs reliability information and the first outer message data. The second inner decoder processes the reliability information and the first outer message data from the first outer decoder and the parity data from the first inner decoder to output the second inner message data obtained by decoding the first outer message data. The second outer decoder decodes the second outer decoder.
