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 meant by spatial multiplexing and spatial diversity?

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 spatial diversity gain?

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 are space diversity methods?

Space Diversity is a technique in which multiple numbers of antennas are used at transmitter and receiver side. As far as detection techniques are concerned, we have used two detection techniques (a) joint minimum mean square error (JMMSE) (b) maximal receive ratio combining (MRRC).
