  2. Multi-user MIMO - Wikipedia

    en.wikipedia.org/wiki/Multi-user_MIMO

    Multi-user MIMO (MU-MIMO) is a set of multiple-input and multiple-output (MIMO) technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another. In contrast, single-user MIMO (SU-MIMO) involves a single multi-antenna-equipped user or terminal ...

  3. MIMO - Wikipedia

    en.wikipedia.org/wiki/MIMO

    [1] [2] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi 4), IEEE 802.11ac (Wi-Fi 5), HSPA+ (3G), WiMAX, and Long Term Evolution (LTE). More recently, MIMO has been applied to power-line communication for three-wire installations as part of the ITU G.hn standard and of the HomePlug AV2 ...

  4. 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 ...

  5. 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 ...

  6. 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 ...

  8. Multipacket reception - Wikipedia

    en.wikipedia.org/wiki/Multipacket_reception

    Multipacket reception. In networking, multipacket reception refers to the capability of networking nodes for decoding/demodulating signals from a number of source nodes concurrently. In wireless communications, Multipacket reception is achieved using physical layer technologies like orthogonal CDMA, MIMO and space–time codes .

  9. WiMAX MIMO - Wikipedia

    en.wikipedia.org/wiki/WiMAX_MIMO

    WiMAX is the technology brand name for the implementation of the standard IEEE 802.16, which specifies the air interface at the PHY (Physical layer) and at the MAC (Medium Access Control layer) . Aside from specifying the support of various channel bandwidths and adaptive modulation and coding, it also specifies the support for MIMO antennas to ...
