– Classic Low-Density Parity-Check (LDPC) codes have recently been used as component codes in Multilevel Coding (MLC) due to their impressive BER performance as well as owing to ...
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...
−A class of combinatorial structures, called absorbing sets, strongly influences the performance of low-density paritycheck (LDPC) decoders. In particular, the quantization schem...

-- 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...
