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…
Locally Best Invariant Test for Multiple Primary User Spectrum Sensing
Lu Wei, Prathapasinghe Dharmawansa, Olav Tirkkonen
We consider multi-antenna cooperative spectrum sensing in cognitive radio networks, when there may be multiple primary users. A noise-uncertainty-free detector that is optimal in t…
Algebraic Fast-Decodable Relay Codes for Distributed Communications
Camilla Hollanti, Nadya Markin
In this paper, fast-decodable lattice code constructions are designed for the nonorthogonal amplify-and-forward (NAF) multiple-input multiple-output (MIMO) channel. The constructio…
On the Exact Distribution of the Scaled Largest Eigenvalue
Lu Wei, Olav Tirkkonen, Prathapasinghe Dharmawansa +1
In this paper we study the distribution of the scaled largest eigenvalue of complexWishart matrices, which has diverse applications both in statistics and wireless communications.…
