Title

Hardware/Software Implementation Of Software Defined Radio(SDR) Applications In Engineering


Abstract

Current technology and policy have created an apparent spectrum scarcity, a situation in which it seems there is not enough available RF spectrum to deploy the next generation of wireless services. It has been shown that this appearance is incorrect because the majority of licensed spectrum is unutilized. In order to address this problem a new technology, the spectrum sensing software radio. This idea has sparked a range of new technologies and algorithms for supporting dynamic spectrum access. The term software defined radio (SDR)first appeared in Joseph Mitola's 1991 paper Software Radios: Survey, Critical Evaluation and Future Directions". Mitola introduces the concept of applying digital signal processing (DSP) on general purpose hardware and using digital to analog converters (DAC) to build digital communications systems. The API developed for specific interfaces for general purpose processors (GPPs, defined as any processors supporting CORBA), digital signal processors (DSPs), and FPGAs, down to timing diagrams for communicating with FPGA buffers. It is use to define the manner in which hardware and software components interact. SDR technology should be seen as an enabler rather than a system technology, if properly applied, it will facilitate reconfigurability and run-time reconfiguration, and eventually cognitive radio.
