A Case Study of a MIMO SDR Implementation
Source: University of California
Funded by a research contract from the Boeing Company, the authors report on the implementation of a Multiple-Input Multiple-Output (MIMO) Software Defined Radio (SDR) platform forming an operational Mobile Ad-Hoc NETworks (MANET) node. The SDR platform utilizes Universal Software Radio Peripheral (USRP) including a motherboard for baseband processing, two daughter boards for RF frontend processing, and an embedded Intel Core General Purpose Processing (GPP) unit hosting Linux operating system. They use GNU Radio to program the PHY and DATA LINK layers of USRP. They also implement the TCP/IP stack on the SDR using the TAP/TUN driver of the Linux Kernel.
