Abstract :
A software defined cognitive radio prototype that consists of a hardware platform and a software platform has been developed. The hardware platform consists of a multi-band antenna supported from UHF band and 2-5 GHz band, multiband RF unit, signal processing unit consists of FPGA and CPU boards. The software platform consists of several managers that manage spectrum sensing and reconfiguration of communication systems by changing software packages. The software packages (called as "waveform") configure specified wireless communication systems and consist of physical layer, MAC/DLC layer, IP layer, and application layer part of the systems. This paper introduces the configuration of the hardware and software platforms and addresses a measurement result of spectrum sensing period and reconfiguration period by using software packages of W-CDMA and IEEE802.11a.
