The Oval Strikes Back
Andrea Di Giusto, Alberto Ravagnani, Emina Soljanin
We investigate the applications of ovals in projective planes to distributed storage, with a focus on the Service Rate Region problem. Leveraging the incidence relations between li…
A distance-free approach to generalized weights
Andrea Di Giusto, Elisa Gorla, Alberto Ravagnani
We propose a unified theory of generalized weights for linear codes endowed with an arbitrary distance. Instead of relying on supports or anticodes, the weights of a code are defin…
Equivalence of Serial and Parallel A-Posteriori Probabilities in the Decoding of DAB Systems
Andrea Di Giusto, Wim van Houtum, Alberto Ravagnani +1
Motivated by applications to digital audio broadcasting (DAB) systems, we study the a-posteriori probabilities (APPs) of the coded and information bits of the serial concatenation…
Bounds and Codes for General Phased Burst Errors
Sebastian Bitzer, Andrea Di Giusto, Alberto Ravagnani +1
Phased burst errors (PBEs) are bursts of errors occurring at one or more known locations. The correction of PBEs is a classical topic in coding theory, with prominent applications…
