On the Application of the Baum-Welch Algorithm for Modeling the Land Mobile Satellite Channel
Balazs Matuz, Francisco Lazaro Blasco, Gianluigi Liva
Accurate channel models are of high importance for the design of upcoming mobile satellite systems. Nowadays most of the models for the LMSC are based on Markov chains and rely on…
On the Concatenation of Non-Binary Random Linear Fountain Codes with Maximum Distance Separable Codes
Francisco Lazaro Blasco, Gianluigi Liva
A novel fountain coding scheme has been introduced. The scheme consists of a parallel concatenation of a MDS block code with a LRFC code, both constructed over the same field, $F_q…
High Throughput Random Access via Codes on Graphs: Coded Slotted ALOHA
Enrico Paolini, Gianluigi Liva, Marco Chiani
In this paper, coded slotted ALOHA (CSA) is introduced as a powerful random access scheme to the MAC frame. In CSA, the burst a generic user wishes to transmit in the MAC frame is…
Turbo Codes Based on Time-Variant Memory-1 Convolutional Codes over Fq
Gianluigi Liva, Enrico Paolini, Sandro Scalise +1
Two classes of turbo codes over high-order finite fields are introduced. The codes are derived from a particular protograph sub-ensemble of the (dv=2,dc=3) low-density parity-check…
