IK4-Ikerlan Selects Nutaq's Radio420X For Reconfigurable Cognitive Radio SystemView Radio420X DetailsThe use of the Nutaq Radio420S radio card as a wireless transceiver on the software defined platform is very interesting because of the wide frequency range, on-the-fly possibility to change the bandwidth and other state-of-the-art features that it offers.

The Centre for Wireless Communications (CWC) at the University of Oulu, in Oulu, Finland, recently selected Nutaq’s Radio420S for use in its white space research as the RF front-end for its Xilinx ML605-based software-defined radio (SDR) research platform.

The mission of the CWC is to conduct world-class research, train world-class graduates, create new technology and support industry. The CWC aims at being one of the leading research institutes globally in the area of wireless communications.

Why the CWC Chose Nutaq’s Radio420S

The CWC choose the Radio420S because they needed an FPGA mezzanine card (FMC) that was compatible with their Xilinx ML605 Virtex-6 FPGA board and could meet their selectable bandwidth requirements. The CWC plans to first integrate the Radio420S to work with their real-time spectrum-sensing algorithm, a localization algorithm based on double-thresholding (LAD) with adjacent cluster combining (ACC). Next, they plan to use it as the final platform for their cognitive radio solution that takes advantage of available white space spectrum.

“The use of the Nutaq Radio420S radio card as a wireless transceiver on the software defined platform is very interesting because of the wide frequency range, on-the-fly possibility to change the bandwidth and other state-of-the-art features that it offers,” wrote the CWC’s Tuomo Hänninen. The combined processing power of the ML605’s Virtex-6 FPGA with the agile and broadband RF front-end of the Radio420S results in an ideal SDR platform for use in the development and real-world testing of their wireless communication algorithms.

Combined together, the programmable hardware and software enables fast reconfiguration of the transceiver and will enable the CWC to easily and rapidly prototype and develop new wireless algorithms.
