An Experimental Study on Indoor Massive 3D-MIMO Channel at 30-40 GHz Band [Elektronisk resurs]

, 2018
Three-dimensional (3D) multiple-input multiple-output (MIMO) channel sounder measurements are producposed for a multi-user MIMO channel at the 30-40 GHz mm-wave band. A 3D-MIMO downlink transmissions links withto two users is considered.
