Massive MIMO: How many antennas do we need?
, 2011 We consider a multicell MIMO uplink channel where each base station (BS) is equipped with a large number of antennas N. The BSs are assumed to estimate their channels based on pilot sequences sent by the user terminals (UTs).

Multiuser MIMO Indoor Visible Light Communications [PDF]
, 2017 Visible light communications (VLC) is an energy efficient and cost-effective solution for indoor wireless multiple access and a candidate technique to provide high-speed data transmissions. VLC systems are built as dual systems (illumination and data transmission) and have potentially higher privacy than RF communication systems due to the natural ...
