MIMO (multiple-in, multiple-out) takes advantage of
multiplexing to increase wireless
bandwidth and range. MIMO
algorithms send information out over two or more antennas and the
information is received via multiple antennas as well. On normal radio,
multiplexing would cause interference, but MIMO uses the additional pathways to
transmit more information and then recombines the signal on the receiving end.
MIMO systems provide a significant capacity gain over conventional single
antenna systems, along with more reliable communication. The benefits of MIMO
lead many to believe it is the most promising of emerging wireless technologies.
An Overview of MIMO Communications (PDF) This paper provides an overview of an emerging technology, known as multiple-input multiple-output (MIMO) wireless that offers significant promise in making 1Gbps wireless links in NLOS environments a reality.
Research on Multi-Antenna and MIMO Wireless Systems In wireless mobile radio communication, there is an endless quest for increased capacity and improved quality. Within this area, we have during the last years studied ways to utilize antennas with multiple elements in an intelligent way.
