Study on Intelligent Reflecting Surface Under Vehicular Communications with Different Threshold

This paper explores two groundbreaking technologies in wireless communication, namely Intelligent Reflecting Surfaces (IRS) and Vehicular Communication. IRS utilizes planar surfaces with passive reflecting elements to induce amplitude and phase changes in incident signals, revolutionizing wireless channel reconfiguration. By flexibly reconfiguring signal propagation, IRS holds promise in addressing channel fading and interference issues, thereby boosting wireless communication capacity and reliability. Vehicular Communication, on the other hand, establishes a computer network in which vehicles and roadside units act as communication nodes, sharing safety warnings and traffic information. V2V, V2I, and V2X technologies enable effective communication between vehicles and infrastructure, aiming to improve road safety and enhance integration between diverse services. Additionally, the abstract highlights the quantization effect of phase shift in IRS, the relationship between power and rate in wireless transmission, and the rapid convergence of algorithms used in IRS optimization. The combination of IRS and Vehicular Communication opens new avenues for seamless, efficient, and reliable wireless communication systems with widespread applications in various domains.
