Well-Rounded Lattices for Coset Coding in MIMO Wiretap Channels
Oliver W. Gnilke, Amaro Barreal, Alex Karrila +3
The concept of well-rounded lattices has recently found important applications in the setting of a fading single-input single-output (SISO) wiretap channel. It has been shown that,…
Information Bounds and Flatness Factor Approximation for Fading Wiretap MIMO Channels
Amaro Barreal, Alex Karrila, David Karpuk +1
In this article, the design of secure lattice coset codes for general wireless channels with fading and Gaussian noise is studied. Recalling the eavesdropper's probability and info…
Reduced Complexity Decoding of n x n Algebraic Space-Time Codes
Amaro Barreal, Camilla Hollanti, David Karpuk
Algebraic space-time coding allows for reliable data exchange across fading multiple-input multiple-output channels. A powerful technique for decoding space-time codes in Maximum-L…
Node Repair for Distributed Storage Systems over Fading Channels
David Karpuk, Camilla Hollanti, Amaro Barreal
Distributed storage systems and associated storage codes can efficiently store a large amount of data while ensuring that data is retrievable in case of node failure. The study of…
Algebraic Codes and a New Physical Layer Transmission Protocol for Wireless Distributed Storage Systems
Amaro Barreal, Camilla Hollanti, David Karpuk +1
In a wireless storage system, having to communicate over a fading channel makes repair transmissions prone to physical layer errors. The first approach to combat fading is to utili…
Space-Time Storage Codes for Wireless Distributed Storage Systems
Camilla Hollanti, David Karpuk, Amaro Barreal +1
Distributed storage systems (DSSs) have gained a lot of interest recently, thanks to their robustness and scalability compared to single-device storage. Majority of the related res…
