PROJECT TITLE :
Testing software defined and cognitive radios using software defined synthetic instruments
Software Defined Radios (SDRs) are wireless communication systems in which many of the radios??? vital useful components, including filtering, frequency translation and modulation/demodulation, are implemented in software via Digital Signal Processing (DSP) techniques using embedded processors and Field Programmable Gate Arrays (FPGA) as described by Harris and Lowdermilk in 2010 [one]. SDRs differ from ancient radios that sometimes employ custom silicon to implement such functions. SDRs exhibit many advantages over traditional radios, including re-configurability and reduced development prices and time-to-market since they do not need custom silicon. SDRs also get pleasure from long life cycles, since they can readily be tailored to satisfy future desires. Cognitive Radios (CRs) are a special class of SDRs that employ adaptive DSP technologies to implement spectral management. This enables CRs to deliver improved effective bandwidth, quality of service, and enhanced security, which became increasingly necessary in fashionable commercial and military wireless communications applications.
