As more devices are connected wirelessly, the need for wireless technologies that can handle increased data and capacity demands has grown exponentially.
As more devices are connected wirelessly, the need for wireless
technologies that can handle increased data and capacity demands
has grown exponentially. The coming onslaught of Internet of Things
(IoT) devices threatens to overwhelm existing wireless networks
while the proliferation of video streaming and virtual reality
technology requires faster data rates than are currently available.
Multiple input, multiple output (MIMO) is one technology that has
the potential to solve these problems by enabling the next
generation of wireless. By using more than one antenna, multiple
data signals can be sent in the same time and frequency domain to
offer huge gains in capacity, throughput, reliability, or a
combination of the three. As leading researchers and wireless
companies rush to explore new communications technologies, MIMO
will be a crucial topic.
Some of the theory behind MU-MIMO and Massive MIMO has been laid out, but researchers need to innovate faster by building real-world prototypes. The NI MIMO Prototyping System is a testbed that enables researchers to prototype these 5G MIMO systems and achieve rapid results.
MIMO Prototyping System Hardware
The MIMO Prototyping System includes USRP RIO radio heads, FlexRIO FPGA co-processors, clock distribution modules, PCIe routing hardware, and a PXIe chassis and controller. The system can be configured in a variety of sizes to meet the requirements of a wide range of MIMO applications including single user MIMO (SU-MIMO), multiple user MIMO (MU-MIMO), and Massive MIMO. The various system components and configurations will be discussed in detail in this paper. Application software is discussed in MIMO Application Framework white paper.
USRP Software Defined Radio
The USRP RIO software defined radio (SDR) features an integrated 2x2 MIMO transceiver and a high-performance Xilinx Kintex-7 FPGA, all contained in a half-width 1U rack-mountable enclosure, to accelerate baseband proces...
