Abstract— In this contribution, we investigate the attainable performance of quasi-cyclic (QC) protograph Low-Density Parity-Check (LDPC) codes for transmission over both Additiv...
Skew Hadamard designs (4n-1, 2n-1, n-1) are associated to order 4n skew Hadamard matrices in the natural way. We study the codes spanned by their incidence matrices A and by I +A a...
Abstract— In this paper, we present a new description of the XCode, a class of MDS array code, using skews, named S-Code. The X-Codes result in codewords that are arrays of size ...
We construct various classes of low-density parity-check codes using point-line incidence structures in the classical projective plane PG(2, q). Each incidence structure is based ...
