Low Complexity-Based Block Selection Scheme for RIS-Assisted Wireless Systems

A low-complexity scheme integrating RIS block selection with adaptive beamforming and a deep neural network (DNN)-based prediction architecture that avoids the exponential complexity growth typically associated with an increasing number of reflecting elements is proposed.

Variational Bayesian Near-Field Channel Estimation for Distributed MIMO Systems

Distributed multiple-input multiple-output (MIMO) is a promising architecture for future wireless systems because cooperation among geographically separated base stations (BSs) improves coverage, spectral efficiency, and link reliability. However, the large effective aperture formed by distributed BSs makes near-field...
