Intelligent Reflecting Surface-Aided Wireless Communications: A Tutorial
TL;DR: This paper provides a tutorial overview of IRS-aided wireless communications, and elaborate its reflection and channel models, hardware architecture and practical constraints, as well as various appealing applications in wireless networks.
Journal ArticleDOI
Intelligent Reflecting Surface Meets OFDM: Protocol Design and Rate Maximization
TL;DR: In this article, an IRS-enhanced orthogonal frequency division multiplexing (OFDM) system under frequency-selective channels is considered and a practical transmission protocol with channel estimation is proposed.
Journal ArticleDOI
Capacity Characterization for Intelligent Reflecting Surface Aided MIMO Communication
Shuowen Zhang,Rui Zhang +1 more
TL;DR: In this article, the fundamental capacity limit of RIS-aided point-to-point multiple-input multiple-output (MIMO) communication systems with multi-antenna transmitter and receiver in general, by jointly optimizing the IRS reflection coefficients and the MIMO transmit covariance matrix, is characterized.
Journal ArticleDOI
Cellular-Enabled UAV Communication: A Connectivity-Constrained Trajectory Optimization Perspective
TL;DR: This paper proposes an efficient method to verify its feasibility via checking the connectivity between two given vertices on an equivalent graph, and obtains useful structural results on the optimal UAV trajectory, based on which two efficient methods are proposed to find high-quality approximate trajectory solutions by leveraging the techniques from graph theory and convex optimization.
