What is spatial diversity in MIMO?

Spatial diversity is a technique in MIMO that reduces signal fading by sending multiple copies of the same radio signal through multiple antennas; spatial multiplexing is a technique in MIMO that boosts data rates by sending the data payload in separate streams through spatially separated antennas.

How space diversity is achieved in MIMO?

Antenna diversity for MIMO

Fundamentally, diversity coding sends multiple copies through multiple transmit antennas, so as to improve the reliability of the data reception. If one of them fails to receive, the others are used for data decoding. MIMO achieves spatial diversity and spatial multiplexing.

What is the difference between MIMO transmit diversity and MIMO spatial multiplexing?

What is different between Spatial Multiplexing and Transmit Diversity in MIMO system? In short: Spatial: send different data from multiple antennas, so increase your throughput. Diversity: send same data from multiple antennas, increase data correction rate.

What is spatial multiplexing gain MIMO?

Spatial multiplexing gain. MIMO channels offer a linear increase in capacity without additional power or bandwidth. This gain is referred as spatial multiplexing gain. The spatial multiplexing gain is realized by transmitting independent data signals from individual antennas.
