Two-Timescale, Low-Overhead Parametric Channel Estimation for RIS-Assisted Near-Field Communication and Its Rate Implications

New techniques are required to estimate the user-to-reconfigurable intelligent surface (RIS) near-field channel due to the distance-dependency of its steering vector. The estimate is needed to determine the RIS configuration and the combining vector of the multi-antenna base station (BS) receiver. We present a novel, l...

Convergence of Over-the-Air Federated Learning With Imperfect Channel Estimates: A Unified View

Over-the-air computation-assisted federated learning (OTA-FL) exploits the superposition property of the wireless channel to markedly reduce the latency and bandwidth requirements of federated learning. Devices adapt their transmit power to enable over-the-air aggregation of the local models. However, imperfect channel...
