Spectral Graph Analysis of Quasi-Cyclic Codes
Roxana Smarandache, Mark F. Flanagan
In this paper we analyze the bound on the additive white Gaussian noise channel (AWGNC) pseudo-weight of a (c,d)-regular linear block code based on the two largest eigenvalues of H…
Absdet-Pseudo-Codewords and Perm-Pseudo-Codewords: Definitions and Properties
Roxana Smarandache, Pascal O. Vontobel
The linear-programming decoding performance of a binary linear code crucially depends on the structure of the fundamental cone of the parity-check matrix that describes the code. T…
Decoding of MDP Convolutional Codes over the Erasure Channel
Virtudes Tomás, Joachim Rosenthal, Roxana Smarandache
This paper studies the decoding capabilities of maximum distance profile (MDP) convolutional codes over the erasure channel and compares them with the decoding capabilities of MDS…
Quasi-Cyclic LDPC Codes: Influence of Proto- and Tanner-Graph Structure on Minimum Hamming Distance Upper Bounds
Roxana Smarandache, Pascal O. Vontobel
Quasi-cyclic (QC) low-density parity-check (LDPC) codes are an important instance of proto-graph-based LDPC codes. In this paper we present upper bounds on the minimum Hamming dist…
