METHOD OF HIGH SPEED TURBO PRODUCT CODE DECODING ALGORITHM

摘要

PURPOSE: A high speed encoding-decoding algorithm is provided to implement a high speed system by simply configuring a structure of a decoder. CONSTITUTION: Decoding on a horizontal/vertical decoder is performed in parallel and a decoding delay is half of an existing method. A metric is external information of a received signal about a horizontal/vertical code word. Decoding about each block is completed and decoding is performed by exchanging external information. Decoding about the horizontal/vertical, an updated signal vector is transmitted to an input for the next repetition.
