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…
Multichannel sparse recovery of complex-valued signals using Huber's criterion
Esa Ollila
In this paper, we generalize Huber's criterion to multichannel sparse recovery problem of complex-valued measurements where the objective is to find good recovery of jointly sparse…
New Lower Bounds for the Shannon Capacity of Odd Cycles
K. Ashik Mathew, Patric R. J. Östergård
The Shannon capacity of a graph is defined as where is the independence number of . The Shannon capacity of the cycle $C_…
A Sensing Policy Based on Confidence Bounds and a Restless Multi-Armed Bandit Model
Jan Oksanen, Visa Koivunen, H. Vincent Poor
A sensing policy for the restless multi-armed bandit problem with stationary but unknown reward distributions is proposed. The work is presented in the context of cognitive radios…
State-Space Inference for Non-Linear Latent Force Models with Application to Satellite Orbit Prediction
Jouni Hartikainen, Mari Seppanen, Simo Sarkka
Latent force models (LFMs) are flexible models that combine mechanistic modelling principles (i.e., physical models) with non-parametric data-driven components. Several key applica…
