2. MIMO-OFDM - Wikipedia

   en.wikipedia.org/wiki/MIMO-OFDM

   Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...

   en.wikipedia.org/wiki/Smart_antenna

   Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.

   Single-input single-output (SISO) [36] is a conventional radio system where neither transmitter nor receiver has multiple antennas. Principal single-user MIMO techniques Bell Laboratories Layered Space-Time (BLAST), Gerard. J. Foschini (1996) Per Antenna Rate Control (PARC), Varanasi, Guess (1998), Chung, Huang, Lozano (2001)

   Research papers suggest that 5G networks are likely to consist of small distributed cells operating at frequencies up to 90 GHz using “massive MIMO.” According to Jakob Hoydis of Bell Laboratories, Alcatel-Lucent , Germany, “Network densification is the only solution to the capacity crunch.”

7. Multi-user MIMO - Wikipedia

   en.wikipedia.org/wiki/Multi-user_MIMO

   Multi-user MIMO (MU-MIMO) is a set of multiple-input and multiple-output (MIMO) technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another. In contrast, single-user MIMO (SU-MIMO) involves a single multi-antenna-equipped user or terminal ...
