Is OFDM used in MIMO?

MIMO-OFDM is also used in the 802.11ac standard and is expected to play a major role in 802.11ax and fifth generation (5G) mobile phone systems. Several early papers on multi-user MIMO were authored by Ross Murch et al.

What is the working principle of OFDM?

Working Principle of OFDM

OFDM is a specialised FDM having the constraint that the sub-streams in which the main signal is divided, are orthogonal to each other. Orthogonal signals are signals that are perpendicular to each other. A main property of orthogonal signals is that they do not interfere with each other.
