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.

What is meant by spatial diversity?
Antenna diversity, also known as space diversity or spatial diversity, is any one of several wireless diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link.
What is diversity and multiplexing?
Diversity and Spatial-Multiplexing
Existence of multiple antennas in a system, means existence of different propagation paths. Aiming at improving the reliability of the system, we may choose to send same data across the different propagation (spatial) paths. This is called spatial diversity or simply diversity.
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 technique?
Spatial multiplexing in wireless communications is based on multi-input and multiple-output (MIMO) technology where multiple antennas at both the transmitter and receiver are used to carry multiple data streams simultaneously within the same frequency band.
