Title: Using Channel Correlation Properties to Improve the Performance of MIMO Systems

Speaker: Egor Endovitskiy, IITP RAS, MIPT

Abstract: Multiple-Input Multiple-Output (MIMO) transmission is one of the key techniques for improving the performance of modern wireless networks, including Wi-Fi networks. Its efficiency largely depends on how accurately and timely the transmitter obtains channel state information. However, a complete description of a MIMO channel may introduce substantial overhead, especially in broadband OFDM systems with many antennas, subcarriers, and users. The presentation will feature the main results of the PhD thesis dedicated to using spatial, temporal, and frequency-domain correlation properties of a MIMO channel to reduce the dimensionality of its representation without significantly affecting its important properties. Specifically, the talk will cover an approach for accelerating the computation of the frequency response of a spatially consistent MIMO channel model, a method for compressing broadband MIMO channel state information using non-uniformly selected interpolation nodes, and a comparative analysis of explicit and implicit MIMO channel sounding mechanisms in Wi-Fi networks, taking into account channel aging, residual uplink-downlink non-reciprocity, and dynamic MIMO configuration selection.

Bio: Egor Endovitskiy received his Master’s degree in Applied Mathematics and Physics from the Moscow Institute of Physics and Technology (MIPT) in 2022. Currently, he is a researcher at the Wireless Networks Lab of the Institute for Information Transmission Problems of the Russian Academy of Sciences (IITP RAS) and a PhD student at MIPT, where he is preparing to defend his PhD thesis in Telecommunication Systems, Networks, and Devices under the supervision of Dr. Evgeny Khorov. His research interests include MIMO channel modeling, methods for improving Wi-Fi network performance, channel state information compression and update mechanisms, and simulation-based analysis of wireless communication systems.
