Benefits of MIMO technology

MIMO(Multiple Input Multiple Output) is technology which can provide significant advantage in system capabilities (Mostly in Throughput, Reliability and Capacity). Any MIMO implementation will take use of mostly below benefits.

Diversity Gain: Arises out of the provision of multiple antennas at the transmitting and/or receiving end of the radio link. This will create multiple transmission paths which minimizes fading effects. The result in an overall improvement in SINR and leading to increased Overall Channel Throughput.

Array Gain: Refers to the beamforming capability of a multiple antenna array. With Suitable signaling of feedback from the receiver , or with measurements made on a return link, it is possible to direct radiated energy towards the receiver in a steered beam. The results is improved channel performance and increased throughput.

Spatial Multiplexing Gain: Rises out of the orthogonality  Between the multiple transmission path created by the multiple antenna array. Since the receiver can resolve independent transmission paths it is possible to map different information streams into the transmission paths: differentiated by their spatial signature. This result in direct increase in the channel throughput in proportion to the number of separated transmission used.
