Low Complexity Antenna Selection for an Intelligent Reflecting Surface Aided Communication System

Explore a technical lecture on antenna selection techniques for intelligent reflecting surface (IRS) aided communication systems, delivered by Prof. Sarvendranath Rimalapudi from IIT Guwahati. Dive into the innovative approach of using passive reflective elements instead of active radio frequency chains to reduce costs and energy consumption in next-generation wireless communication. Learn about transmit antenna selection (AS) technology and its role in reducing RF chains while maintaining multiple antenna benefits. Understand the challenges of pilot transmissions in combining AS and intelligent reflecting surfaces, examining both optimal and simplified selection rules for single AS scenarios. Discover manifold optimization-based algorithms and alternating optimization techniques for subset AS that reduce complexity while maintaining near-optimal performance. Gain insights into cutting-edge research that bridges multiple antenna techniques with emerging IRS technology for future wireless communication systems.
