FPGAs in software defined radio

Software defined radio (SDR) technology has been gaining more prominence today as it is the design which includes very minimal hard-wired analog components and more software programmable functions. The reconfigurability of SDR enables this technology applicable across a wide range of areas within the wireless industry. The re-usability and flexibility of SDR depends on the FPGA it uses. This paper concentrates on how various components SDR are implemented using FPGA and also gives a note of comparison analysis of FPGAs offered by various vendors.
