Multiple Hypothesis Testing Framework for Spatial Signals
Martin Gölz, Abdelhak M. Zoubir, Visa Koivunen
The problem of identifying regions of spatially interesting, different or adversarial behavior is inherent to many practical applications involving distributed multisensor systems.…
Reinforcement Learning for Physical Layer Communications
Philippe Mary, Visa Koivunen, Christophe Moy
In this chapter, we will give comprehensive examples of applying RL in optimizing the physical layer of wireless communications by defining different class of problems and the poss…
Bayesian Quickest Detection of Propagating Spatial Events
Topi Halme, Eyal Nitzan, Visa Koivunen
Rapid detection of spatial events that propagate across a sensor network is of wide interest in many modern applications. In particular, in communications, radar, IoT, environmenta…
MIMO-OFDM Joint Radar-Communications: Is ICI Friend or Foe?
Musa Furkan Keskin, Henk Wymeersch, Visa Koivunen
Inter-carrier interference (ICI) poses a significant challenge for OFDM joint radar-communications (JRC) systems in high-mobility scenarios. In this paper, we propose a novel ICI-a…
ICI-Aware Parameter Estimation for MIMO-OFDM Radar via APES Spatial Filtering
Musa Furkan Keskin, Henk Wymeersch, Visa Koivunen
We propose a novel three-stage delay-Doppler-angle estimation algorithm for a MIMO-OFDM radar in the presence of inter-carrier interference (ICI). First, leveraging the observation…
