Other AbstractAn Overlapped Layered-BP(OLBP) decoding algorithm is proposed aiming at further increasing the convergence speed and enhancing the error performance of the Layered Belief-Propagation(LBP) algorithm. In this algorithm, more than one sub-decoders are used to decode simultaneously, and sub-decoders have different check node updating orders from each other. The most reliable messages are kept and used for the next iteration for every check node, and thus a faster convergence can be provided. Simulation result shows that, compared with the LBP algorithm, the OLBP algorithm possesses a better error performance as well as a higher convergence speed and introducing no extra storage requirement. Moreover, the proposed algorithm is effective for both regular and irregular LDPC codes.
