Joint Channel Estimation and Cooperative Localization for Near-Field Ultra-Massive MIMO
arXiv:2312.13683v2 Announce Type: replace-cross Abstract: The next-generation wireless networks are envisioned to jointly support high-rate communications and ubiquitous sensing. Ultra-Massive Multiple-Input Multiple-Output (UM-MIMO) offers abundant spatial Degrees of Freedom (DoFs) for both functions, yet its large aperture shifts electromagnetic propagation into the near field, invalidating conventional far-field (plane-wave) assumptions. While near-field channel modeling has been studied,...
