Array Convolutional Low-Density Parity-Check Codes
Marco Baldi, Giovanni Cancellieri, Franco Chiaraluce
This paper presents a design technique for obtaining regular time-invariant low-density parity-check convolutional (RTI-LDPCC) codes with low complexity and good performance. We st…
Advanced channel coding for space mission telecommand links
Marco Baldi, Marco Bianchi, Franco Chiaraluce +3
We investigate and compare different options for updating the error correcting code currently used in space mission telecommand links. Taking as a reference the solutions recently…
Advanced coding schemes against jamming in telecommand links
Marco Baldi, Marco Bianchi, Franco Chiaraluce +4
The aim of this paper is to study the performance of some coding schemes recently proposed for updating the TC channel coding standard for space applications, in the presence of ja…
On a Family of Circulant Matrices for Quasi-Cyclic Low-Density Generator Matrix Codes
Marco Baldi, Federico Bambozzi, Franco Chiaraluce
We present a new class of sparse and easily invertible circulant matrices that can have a sparse inverse though not being permutation matrices. Their study is useful in the design…
Coding with Scrambling, Concatenation, and HARQ for the AWGN Wire-Tap Channel: A Security Gap Analysis
Marco Baldi, Marco Bianchi, Franco Chiaraluce
This study examines the use of nonsystematic channel codes to obtain secure transmissions over the additive white Gaussian noise (AWGN) wire-tap channel. Unlike the previous approa…
Improving the efficiency of the LDPC code-based McEliece cryptosystem through irregular codes
Marco Baldi, Marco Bianchi, Nicola Maturo +1
We consider the framework of the McEliece cryptosystem based on LDPC codes, which is a promising post-quantum alternative to classical public key cryptosystems. The use of LDPC cod…
