GENERATION OF TANNER GRAPHS FOR SYSTEMATIC GROUP CODES FOR EFFICIENT COMMUNICATION

摘要

A computer implemented method of communicating includes receiving systematic group codes representative of one or more messages. A Tanner graph is used to decode such systematic group codes. A method of forming a communication decoder includes obtaining a dual code for a systematic group code, obtaining a Tanner graph from the dual code, and reducing vertex complexity of the Tanner graph to provide a decoding Tanner graph for the communication decoder.
