Joint Channel and Data Estimation for Multiuser Extremely Large-Scale MIMO Systems

Kabuto Arai, Koji Ishibashi, Hiroki Iimori +2

This paper proposes a joint channel and data estimation (JCDE) algorithm for uplink multiuser extremely large-scale multiple-input-multiple-output (XL-MIMO) systems. The initial ch…
