Joint Port Selection Based Channel Acquisition for FDD Cell-Free Massive MIMO
Cheng Zhang, Pengguang Du, Minjie Ding +2
In frequency division duplexing (FDD) cell-free massive MIMO, the acquisition of the channel state information (CSI) is very challenging because of the large overhead required for…
