On the Probability of Network States with Gaussian Connectivity Functions

Amy S. Inwood, Peter J. Smith, Pawel Dmochowski +3

In this paper, we consider the connectivity of a random network of N mobile devices in three dimensions (3D), where the location of each device or node has a Gaussian distribution…

Beam Squinting Effects in Super Wideband Communication Systems

Sachitha C. Bandara, Peter J. Smith, Erfan Khordad +3

Beam squint, the frequency-dependent shift of the main beam, poses a major challenge for wideband antenna arrays. This paper focuses on the beam squint effects in super wideband (S…

Optimal Phase Design for RIS Channel Estimation

Chelsea L. Miller, Peter J. Smith, Pawel A. Dmochowski

We develop an optimal version of a prior two-stage channel estimation protocol for RIS-assisted channels. The new design uses a modified DFT matrix (MDFT) for the training phases a…

Phase Dependent Loss Analysis for RIS Systems

Ikram Singh, Peter J. Smith, Pawel A. Dmochowski

In this paper we focus on phase dependent loss (PDL), an important aspect of reconfigurable intelligent surfaces (RIS) where the signals reflected from the RIS elements are attenua…

Optimal SNR Analysis for Single-user RIS Systems in Ricean and Rayleigh Environments

Ikram Singh, Peter J. Smith, Pawel A. Dmochowski

We present an analysis of the optimal uplink (UL) SNR of a SIMO Reconfigurable Intelligent Surface (RIS)-aided wireless link. We assume that the channel between base station (BS) a…
