Pseudo-Codeword Performance Analysis for LDPC Convolutional Codes
Roxana Smarandache, Ali E. Pusane, Pascal O. Vontobel +1
Message-passing iterative decoders for low-density parity-check (LDPC) block codes are known to be subject to decoding failures due to so-called pseudo-codewords. These failures ca…
Superregular Matrices and the Construction of Convolutional Codes having a Maximum Distance Profile
R. Hutchinson, R. Smarandache, J. Trumpf
Superregular matrices are a class of lower triangular Toeplitz matrices that arise in the context of constructing convolutional codes having a maximum distance profile. These matri…
Pseudo-Codeword Analysis of Tanner Graphs from Projective and Euclidean Planes
Roxana Smarandache, Pascal O. Vontobel
In order to understand the performance of a code under maximum-likelihood (ML) decoding, one studies the codewords, in particular the minimal codewords, and their Hamming weights.…
