Delay Minimization in Real-time Communications with Joint Buffering and Coding
Jesper H. Sørensen, Petar Popovski, Jan Østergaard
We present a closed-form expression for the minimal delay that is achievable in a setting that combines a buffer and an erasure code, used to mitigate the packet delay variance. Th…
Random Access Protocols for Massive MIMO
Elisabeth de Carvalho, Emil Björnson, Jesper H. Sørensen +2
5G wireless networks are expected to support new services with stringent requirements on data rates, latency and reliability. One novel feature is the ability to serve a dense crow…
Coded Pilot Access: A Random Access Solution for Massive MIMO Systems
Jesper H. Sørensen, Elisabeth de Carvalho, Čedomir Stefanović +1
We present a novel access protocol for crowd scenarios in massive MIMO (Multiple-input multiple-output) systems. Crowd scenarios are characterized by a large number of users with i…
A Random Access Protocol for Pilot Allocation in Crowded Massive MIMO Systems
Emil Björnson, Elisabeth de Carvalho, Jesper H. Sørensen +2
The Massive MIMO (multiple-input multiple-output) technology has great potential to manage the rapid growth of wireless data traffic. Massive MIMO achieves tremendous spectral effi…
