Abstract : Software Defined Radio (SDR) is defined as radio in which some or all of the physical layer functions are software defined. It is a radio system whose components are realized in software rather than in hardware. SDR system provides flexibility and portability. The main idea behind SDR is that more of the waveform processing can be implemented in reprogrammable digital hardware so a single platform can be used for multiple waveforms. Typical implementations of s SDR modems include a general purpose processor (GPP), digital signal processor (DSP) and field programmable gate array (FPGA). In SDR FPGAs can be used as both an interconnect layer and a general-purpose computational fabric implementing hardware acceleration units. The FPGA fabric can be used to offload either the GPP or DSP (or both). This paper discusses the principle of SDR and the platforms used for SDR implementation.
