Compact McEliece keys based on Quasi-Dyadic Srivastava codes
The McEliece cryptosystem is one of the few systems to be considered secure against attacks by Quantum computers. The original scheme is built upon Goppa codes and produces very l...

Low density codes achieve the rate-distortion bound
Abstract: We propose a new construction for low-density source codes with multiple parameters that can be tuned to optimize the performance of the code. In addition, we introduce a...

T-shift synchronization codes
In this paper we give a construction of T-shift synchronization codes, i.e. block codes capable of correcting synchronization shifts of length at most T in either direction (left ...

On the optimum distance profiles about linear block codes
In this paper, for some linear block codes, two kinds of optimum distance profiles (ODPs) are introduced to consider how to construct and then exclude (or include) the basis codewo...
