Unequal Error Protection in Coded Slotted ALOHA
Mikhail Ivanov, Fredrik Brannstrom, Alexandre Graell i Amat +1
We analyze the performance of coded slotted ALOHA systems for a scenario where users have different error protection requirements and correspondingly can be divided into user class…
Density Evolution for Deterministic Generalized Product Codes with Higher-Order Modulation
Christian Häger, Alexandre Graell i Amat, Henry D. Pfister +1
Generalized product codes (GPCs) are extensions of product codes (PCs) where coded bits are protected by two component codes but not necessarily arranged in a rectangular array. It…
Asymptotic and Finite Frame Length Analysis of Frame Asynchronous Coded Slotted ALOHA
Erik Sandgren, Alexandre Graell i Amat, Fredrik Brännström
We consider a frame-asynchronous coded slotted ALOHA (FA-CSA) system where users become active according to a Poisson random process. In contrast to standard frame-synchronous CSA…
Distributed Storage in Mobile Wireless Networks with Device-to-Device Communication
Jesper Pedersen, Alexandre Graell i Amat, Iryna Andriyanova +1
We consider the use of distributed storage (DS) to reduce the communication cost of content delivery in wireless networks. Content is stored (cached) in a number of mobile devices…
