Rayleigh Fading Modeling and Channel Hardening for Reconfigurable Intelligent Surfaces [PDF]
IEEE Wireless Communications Letters, 2020 A realistic performance assessment of any wireless technology requires the use of a channel model that reflects its main characteristics. The independent and identically distributed Rayleigh fading channel model has been (and still is) the basis of most ...

Learning & Memory, 2006 Patient H.M. can form new memories and maintain them for a few seconds before they fade away. From a neurobiological perspective, this amnesia is usually attributed to the absence of memory consolidation, that is, memory storage. An alternative view holds that this impairment reflects that the memory is present but cannot be retrieved.

Federated Learning Over Wireless Fading Channels [PDF]
IEEE Transactions on Wireless Communications, 2019 We study federated machine learning at the wireless network edge, where limited power wireless devices, each with its own dataset, build a joint model with the help of a remote parameter server (PS). We consider a bandwidth-limited fading multiple access

3D Trajectory Optimization in Rician Fading for UAV-Enabled Data Harvesting [PDF]
IEEE Transactions on Wireless Communications, 2019 Dispatching unmanned aerial vehicles (UAVs) to harvest sensing-data from distributed sensors is expected to significantly improve the data collection efficiency in conventional wireless sensor networks (WSNs). In this paper, we consider a UAV-enabled WSN,

Beamforming Through Reconfigurable Intelligent Surfaces in Single-User MIMO Systems: SNR Distribution and Scaling Laws in the Presence of Channel Fading and Phase Noise [PDF]
IEEE Wireless Communications Letters, 2020 We consider a fading channel in which a multi-antenna transmitter communicates with a multi-antenna receiver through a reconfigurable intelligent surface (RIS) that is made of ${N}$ reconfigurable passive scatterers impaired by phase noise.

Reinforcement with Fading Memories [PDF]
SSRN Electronic Journal, 2016 We study the effect of imperfect memory on decision making in the context of a stochastic sequential action-reward problem. An agent chooses a sequence of actions, which generate discrete rewards at different rates. She is allowed to make new choices at rate β, whereas past rewards disappear from her memory at rate μ.

Spatially-Stationary Model for Holographic MIMO Small-Scale Fading [PDF]
IEEE Journal on Selected Areas in Communications, 2019 Imagine an array with a massive (possibly uncountably infinite) number of antennas in a compact space. We refer to a system of this sort as Holographic MIMO. Given the impressive properties of Massive MIMO, one might expect a holographic array to realize
