A Novel Cross-Domain Channel Estimation Scheme for OFDM

Mingcheng Nie, Ruoxi Chong, Shuangyang Li +5

In this paper, we propose a novel cross-domain channel estimation (CDCE) algorithm for orthogonal frequency division multiplexing (OFDM) systems, leveraging the unique characterist…

On the Sensing Capacity of Gaussian "Beam-Pointing" Channels with Block Memory and Feedback

Siyao Li, Shuangyang Li, Giuseppe Caire

Driven by the demands of high-frequency wireless communications in 5G and 6G systems (e.g., mmWave, sub-THz), we explore a state-dependent {\em Gaussian beam-pointing} (GBP) channe…
