Spatial-Temporal BEM and Channel Estimation Strategy for Massive MIMO Time-Varying Systems
Hongxiang Xie, Feifei Gao, Shun Zhang +1
This paper proposes a new channel estimation scheme for the multiuser massive multiple-input multiple-output (MIMO) systems in time-varying environment. We introduce a discrete Fou…

Low-Rank Covariance-Assisted Downlink Training and Channel Estimation for FDD Massive MIMO Systems
Jun Fang, Xingjian Li, Hongbin Li +1
We consider the problem of downlink training and channel estimation in frequency division duplex (FDD) massive MIMO systems, where the base station (BS) equipped with a large numbe…
