2. MIMO - Wikipedia

   en.wikipedia.org/wiki/MIMO

   Single-input single-output (SISO) [36] is a conventional radio system where neither transmitter nor receiver has multiple antennas. Principal single-user MIMO techniques Bell Laboratories Layered Space-Time (BLAST), Gerard. J. Foschini (1996) Per Antenna Rate Control (PARC), Varanasi, Guess (1998), Chung, Huang, Lozano (2001)

3. 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 ...

4. Smart antenna - Wikipedia

   en.wikipedia.org/wiki/Smart_antenna

   Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.

5. History of smart antennas - Wikipedia

   en.wikipedia.org/wiki/History_of_smart_antennas

   Antenna for LTE MIMO technology with 2 connections of offset indoor antennas. Smart antenna research led to the development of 4G MIMO. Conventional smart antenna techniques (such as diversity and beamforming) deliver incremental gains in spectral efficiency. 4G MIMO exploits natural multipath propagation to multiply spectral efficiency.

   These are the QTM052 mmWave antenna module family and the QPM56xx sub-6 GHz radio frequency (RF) module, and they'll pair with the company's previously announced Snapdragon X50 5G modem -- making ...

7. 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 ...
