About 5G MIMO Simulator:
The hardware and software used to generate 5G compliant MIMO signal vectors as per UE and base station specifications is known as 5G MIMO simulator. The figure-1 below depicts baseband and RF chain used during 5G MIMO simulation.

Typical modules used include coding, modulation, beamforming, MIMO processing, IFFT, DAC, RF up conversion, antenna array etc.

Following MIMO modes are usually supported by 4G and 5G Wireless technologies.
• SU-MIMO (Single User MIMO): Supports upto 128 Base Station Antennas, and upto 12 antennas per mobile station. Number of mobile stations used are one.
• MU-MIMO (Multi User MIMO): Supports upto 128 Base Station Antennas, and 8 for MS#1 and 4 for MS#2. Number of movile stations used are two.
• Massive MIMO: Supports upto 128 Base Station Antennas, 5 number of MSs with various antenna configurations (4/4/2/1/1 for MS1, MS2, MS3, MS4 and MS5 consecutively).
