Decentralized Hybrid Precoding for Massive Mu-Mimo Isac

ICC 2025 - IEEE International Conference on Communications
Integrated sensing and communication (ISAC) is a very promising technology designed to provide both high rate communication capabilities and sensing capabilities. However, in Massive Multi User Multiple-Input Multiple-Output (Massive MU MIMO-ISAC) systems, the dense user access creates a serious multi-user interference (MUI) problem, leading to ...
