We consider the uplink of two mobile stations with the help of one common relay. Recently, joint network-channel coding based on LDPC codes was proposed for this setup where the ch...

We study information reconciliation (IR) scheme for the quantum key distribution (QKD) protocols. The IR for the QKD can be considered as the asymmetric Slepian-Wolf problem, which...
Abstract— There is a well-known error-floor phenomenon associated with iterative LDPC decoders which has delayed the use of LDPC codes in certain communication and storage syste...
The performance of punctured LDPC codes under maximum-likelihood (ML) decoding is studied in this paper via deriving and analyzing their average weight distributions (AWDs) and th...
Recent works showed how low-density parity-check (LDPC) erasure correcting codes, under maximum likelihood (ML) decoding, are capable of tightly approaching the performance of an i...

We describe a flexible hardware encoder for regular and irregular low-density parity-check (LDPC) codes. Although LDPC codes achieve achieve better performance and lower decoding ...

The construction of good, finite-length, LDPC codes is currently an attractive research area. Reducing attention to the Binary Erasure Channel (BEC), this problem translates into t...

Low-Density Parity-Check (LDPC) codes have been adopted in the physical layer of many communication systems because of their superior performance. The direct implementation of the...
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...
— In this paper we present protograph codes with a small number of degree-3 nodes and one high degree node. The iterative decoding threshold for proposed rate 1/2 codes are lower...
