2. MIMO - Wikipedia

   en.wikipedia.org/wiki/MIMO

   In radio, multiple-input and multiple-output (MIMO) (/ ˈmaɪmoʊ, ˈmiːmoʊ /) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. [1][2] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi 4), IEEE 802 ...

3. Cooperative MIMO - Wikipedia

   en.wikipedia.org/wiki/Cooperative_MIMO

   Cooperative MIMO. In radio, cooperative multiple-input multiple-output (cooperative MIMO, CO-MIMO) is a technology that can effectively exploit the spatial domain of mobile fading channels to bring significant performance improvements to wireless communication systems. It is also called network MIMO, distributed MIMO, virtual MIMO, and virtual ...

4. Channel state information - Wikipedia

   en.wikipedia.org/wiki/Channel_state_information

   In wireless communications, channel state information (CSI) is the known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance. The method is called channel estimation.

5. MIMO-OFDM - Wikipedia

   en.wikipedia.org/wiki/MIMO-OFDM

   Multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple-input, multiple-output technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into ...

6. IEEE 802.11ac-2013 - Wikipedia

   en.wikipedia.org/wiki/IEEE_802.11ac-2013

   They do not exist in the official nomenclature. [6][7][8] IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [c] The standard has been retroactively labelled as Wi-Fi ...

7. Space-time adaptive processing - Wikipedia

   en.wikipedia.org/wiki/Space-time_adaptive_processing

   Space-time adaptive processing (STAP) is a signal processing technique most commonly used in radar systems. It involves adaptive array processing algorithms to aid in target detection. Radar signal processing benefits from STAP in areas where interference is a problem (i.e. ground clutter, jamming, etc.). Through careful application of STAP, it ...

8. 3G MIMO - Wikipedia

   en.wikipedia.org/wiki/3G_MIMO

   3G MIMO. 3G MIMO describes MIMO techniques which have been considered as 3G standard techniques. MIMO, as the state of the art of intelligent antenna (IA), improves the performance of radio systems by embedding electronics intelligence into the spatial processing unit. Spatial processing includes spatial precoding at the transmitter and spatial ...
