Abstract—A bit-node centric decoder architecture for lowdensity parity-check codes is proposed. This architecture performs the optimum sum-product algorithm. A bit node processin...

Abstract−Several high performance LDPC codes have paritycheck matrices composed of permutation submatrices. We design a parallel-serial architecture to map the decoder of any str...
-- We introduce a thermodynamic (large deviation) formalism for computing error exponents in error-correcting codes. Within this framework, we apply the heuristic cavity method fro...
— Low-Density Parity-Check (LDPC) codes are typically characterized by a relatively high-complexity description, since a considerable amount of memory is required in order to sto...
— Low-Density Parity-Check Convolutional Codes (LDPC-CCs) are an attractive alternative to their block-oriented counterparts, LDPC-BCs. In this paper, we introduce these codes an...
