The idea behind AMC is to dynamically adapt the modulation and coding scheme to the channel conditions to achieve the highest spectral efficiency at all times [2, Chapter 9]. An additional dimension to modulation and coding aimed at increasing spectral efficiency is the space dimension, i.e., the use of multiple antennas at the transmitter and receiver. More generally, multiple-antenna ……
