Deterministic and Ensemble-Based Spatially-Coupled Product Codes
Christian Häger, Henry D. Pfister, Alexandre Graell i Amat +1
Several authors have proposed spatially-coupled (or convolutional-like) variants of product codes (PCs). In this paper, we focus on a parametrized family of generalized PCs that re…
A Family of Erasure Correcting Codes with Low Repair Bandwidth and Low Repair Complexity
Siddhartha Kumar, Alexandre Graell i Amat, Iryna Andriyanova +1
We present the construction of a new family of erasure correcting codes for distributed storage that yield low repair bandwidth and low repair complexity. The construction is based…
Probabilistic Handshake in All-to-all Broadcast Coded Slotted ALOHA
Mikhail Ivanov, Petar Popovski, Fredrik Brannstrom +2
We propose a probabilistic handshake mechanism for all-to-all broadcast coded slotted ALOHA. We consider a fully connected network where each user acts as both transmitter and rece…
Repair Scheduling in Wireless Distributed Storage with D2D Communication
Jesper Pedersen, Alexandre Graell i Amat, Iryna Andriyanova +1
We consider distributed storage (DS) for a wireless network where mobile devices arrive and depart according to a Poisson random process. Content is stored in a number of mobile de…
All-to-all Broadcast for Vehicular Networks Based on Coded Slotted ALOHA
Mikhail Ivanov, Fredrik Brannstrom, Alexandre Graell i Amat +1
We propose an uncoordinated all-to-all broadcast protocol for periodic messages in vehicular networks based on coded slotted ALOHA (CSA). Unlike classical CSA, each user acts as bo…
On Channel Estimation for 802.11p in Highly Time-Varying Vehicular Channels
Keerthi Kumar Nagalapur, Fredrik Brännström, Erik G. Ström
Vehicular wireless channels are highly time-varying and the pilot pattern in the 802.11p orthogonal frequency-division multiplexing frame has been shown to be ill suited for long d…
