Performance Limits of RIS-Assisted MIMO Systems in Nakagami-m Fading Environments
SignalsThis work analyzes the ergodic capacity behavior of reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output (MIMO) systems with a finite and arbitrary number of antennas and RIS elements under Nakagami-m fading conditions.

Full-Duplex Mode in Amplify-and-Forward Relay Channels: Outage Probability and Ergodic Capacity
International Journal of Antennas and Propagation, 2014 This paper investigates the outage probability and ergodic capacity performances for full-duplex mode in two-way amplify-and-forward relay channels. The two-way relay channels which consist of two source nodes and a single relay node working in full ...

On the Ergodic Channel Capacity for Indoor Visible Light Communication Systems
IEEE Access, 2017 Since indoor visible light communication (VLC) modulates the information into the light beams emitted from light-emitting diodes, the channel gain is often modeled as the Lambertian model.

Wave Tracing: Generalizing The Path Integral To Wave Optics
Computer Graphics Forum, EarlyView.Abstract Modeling the wave nature of light and the propagation and diffraction of electromagnetic fields is crucial for the accurate simulation of many phenomena, yet wave simulations are significantly more computationally complex than classical ray‐based models.

Ergodic Secrecy Capacity Region of the Fading Broadcast Channel [PDF]
2009 IEEE International Conference on Communications, 2009 We consider the fading broadcast channel from a secrecy point of view. In this channel, each user views the other user as an eavesdropper, and wants to keep its information as secret from the other user as possible. First, we consider a more general channel model which consists of L independent sub-channels, where in each sub-channel, one of the users'

Twin Defaults and Bank Capital Requirements
The Journal of Finance, EarlyView.ABSTRACT We examine optimal capital requirements in a quantitative general equilibrium model with banks exposed to nondiversifiable borrower default risk. Contrary to standard models of bank default risk, our framework captures the limited upside, but significant downside risk of loan portfolio returns.

Downlink capacity analysis in distributed antenna systems
Tongxin xuebao, 2012 The downlink capacity was analyzed in distributed antenna systems(DAS).Firstly,a composite channel model was established,which took path loss,lognormal shadowing and Rayleigh fading into account.Then,based on the channel model,both the ergodic capacity ...

Testing Distributional Granger Causality With Entropic Optimal Transport
Journal of Time Series Analysis, EarlyView.ABSTRACT We develop a novel nonparametric test for Granger causality in distribution based on entropic optimal transport. Unlike classical mean‐based approaches, the proposed method directly compares the full conditional distributions of a response variable with and without the history of a candidate predictor.
