National Institute of Information and Communications Technology (NICT) has developed a software defined radio platform that consists of FPGA board, CPU board, and RF boards. On the platform, software packages for W-CDMA, IEEE802.11a/b, and digital terrestrial broadcasting have been developed. Each software package consists of physical layer, MAC/DLC layer, IP layer, and application layer part In this paper the details of SDR platform and its software are introduced. Then, the volume of each software package for FPGAs and CPUs is shown and the minimum size of hardware that realizes communication and broadcasting systems with high-signal-processing-power is discussed. Finally, this paper shows the image and requirement of cognitive radio based on the research results
