Intelligent Reflecting Surface assisted wireless communication for coverage enhancement

Intelligent Reflecting Surfaces (IRS) have become a viable technique for improving wireless communication systems' performance and coverage. IRS can successfully regulate the wireless channel and get around issues like signal attenuation, multipath fading, and interference by modifying electromagnetic waves propagation. This paper provides a thorough analysis of how IRS is used in wireless communication systems to increase coverage. It examines several deployment scenarios, looks into the guiding principles of IRS operation, and assesses the performance improvements in terms of achievable rate, brought about by IRS-assisted communication. In order to meet the expanding demands of wireless communication, it is important to build systems that are effective, dependable, and sustainable.
