Construction of Near-Capacity Protograph LDPC Code Sequences with Block-Error Thresholds
Asit Kumar Pradhan, Andrew Thangaraj, Arunkumar Subramanian
Density evolution for protograph Low-Density Parity-Check (LDPC) codes is considered, and it is shown that the message-error rate falls double-exponentially with iterations wheneve…
Deterministic Constructions for Large Girth Protograph LDPC Codes
Asit Kumar Pradhan, Arunkumar Subramanian, Andrew Thangaraj
The bit-error threshold of the standard ensemble of Low Density Parity Check (LDPC) codes is known to be close to capacity, if there is a non-zero fraction of degree-two bit nodes.…
Strong Secrecy on the Binary Erasure Wiretap Channel Using Large-Girth LDPC Codes
Arunkumar Subramanian, Andrew Thangaraj, Matthieu Bloch +1
For an arbitrary degree distribution pair (DDP), we construct a sequence of low-density parity-check (LDPC) code ensembles with girth growing logarithmically in block-length using…
Strong Secrecy for Erasure Wiretap Channels
Ananda T. Suresh, Arunkumar Subramanian, Andrew Thangaraj +2
We show that duals of certain low-density parity-check (LDPC) codes, when used in a standard coset coding scheme, provide strong secrecy over the binary erasure wiretap channel (BE…
MDS codes on the erasure-erasure wiretap channel
Arunkumar Subramanian, Steven W. McLaughlin
This paper considers the problem of perfectly secure communication on a modified version of Wyner's wiretap channel II where both the main and wiretapper's channels have some erasu…
