On Fast-Decodable Algebraic Space--Time Codes
Amaro Barreal, Camilla Hollanti
In the near future, the generation (5G) wireless systems will be established. They will consist of an integration of different techniques, including distributed antenna sy…
Nested Lattice Codes for Vector Perturbation Systems
David A. Karpuk, Amaro Barreal, Oliver W. Gnilke +1
Vector perturbation is an encoding method for broadcast channels in which the transmitter solves a shortest vector problem in a lattice to create a perturbation vector, which is th…
Constructions of Fast-Decodable Distributed Space-Time Codes
Amaro Barreal, Camilla Hollanti, Nadya Markin
Fast-decodable distributed space-time codes are constructed by adapting the iterative code construction introduced in [1] to the N -relay multiple-input multiple-output channel, le…
A Low-Complexity Message Recovery Method for Compute-and-Forward Relaying
Amaro Barreal, Joonas Pääkkönen, David Karpuk +2
The Compute-and-Forward relaying strategy achieves high computation rates by decoding linear combinations of transmitted messages at intermediate relays. However, if the involved r…
