Pseudo-MDP Convolutional Codes for Burst Erasure Correction
Zita Abreu, Julia Lieb, Raquel Pinto
Convolutional codes are a class of error-correcting codes that performs very well over erasure channels with low delay requirements. In particular, Maximum Distance Profile (MDP) c…
Algorithms for Computing the Free Distance of Convolutional Codes
Zita Abreu, Joachim Rosenthal, Michael Schaller
The free distance of a convolutional code is a reliable indicator of its performance. However its computation is not an easy task. In this paper, we present some algorithms to comp…
An Improved Viterbi Algorithm for a Class of Optimal Binary Convolutional Codes
Zita Abreu, Julia Lieb, Michael Schaller
The most famous error-decoding algorithm for convolutional codes is the Viterbi algorithm. In this paper, we present a new reduced complexity version of this algorithm which can be…
A new construction of an MDS convolutional code of rate 1/2
Zita Abreu, Raquel Pinto, Rita Simões
Maximum distance separable convolutional codes are characterized by the property that the free distance reaches the generalized Singleton bound, which makes them optimal for error…
Binary convolutional codes with optimal column distances
Zita Abreu, Julia Lieb, Joachim Rosenthal
There exists a large literature of construction of convolutional codes with maximal or near maximal free distance. Much less is known about constructions of convolutional codes hav…
Criteria for the construction of MDS convolutional codes with good column distances
Zita Abreu, Julia Lieb, Raquel Pinto +1
Maximum-distance separable (MDS) convolutional codes are characterized by the property that their free distance reaches the generalized Singleton bound. In this paper, new criteria…
