Spatial Modulation- Spatial Multiplexing in Massive MIMO

open access: yesCoRR, 2016
Massive MIMO, a candidate for 5G technology, promises significant gains in wireless data rates and link reliability by using large numbers of antennas (more than 64) at the base transceiver station (BTS). Extra antennas help by focusing the transmission and reception of signal energy into ever-smaller regions of space.
