Machine Learning-Assisted Codebook Design for MMSE Channel Estimation

2023 IEEE INTERNATIONAL CONFERENCE ON COMMUNICATIONS WORKSHOPS, ICC WORKSHOPS, pp. 283–288.

By: X. Tian n, Y. Hu *, Y. Li *, T. Wang* & J. Zhang*

author keywords: Machine learning; data-driven; auto-correlation function; MMSE channel estimation; clustering; k-medoids
TL;DR: This work proposes a machine learning-assisted codebook design for minimum meansquare error channel estimation, where ML techniques are applied to cluster the channels that minimize the sum normalized mean square error (MSE). (via Semantic Scholar)

Optimizing the Deployment of Reconfigurable Intelligent Surfaces in MmWave Vehicular Systems

2022 IEEE GLOBAL COMMUNICATIONS CONFERENCE (GLOBECOM 2022), pp. 5261–5266.

By: X. Tian n, N. Gonzalez-Prelcic n & R. Heath n 

author keywords: Reconfigurable intelligent surfaces; millimeter wave; blockages; deployment; vehicular systems
TL;DR: This paper finds the optimal location, height and downtilt of RIS working in a realistic vehicular scenario and finds that the optimized RIS improves the area-averaged rate fifty percent over the case without a RIS, as well as further improvements in the coverage ratio.
