Software Defined Radio (SDR)
Software Defined Radio (SDR) refers to the technology wherein software modules running on a generic hardware platform consisting of DSPs and general purpose microprocessors are used to implement radio functions such as generation of transmitted signal (modulation) at transmitter and tuning/detection of received radio signal (demodulation) at receiver.You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.
SDR technology facilitates implementation of some of the functional modules in a radio system such as modulation/demodulation, signal generation, coding and link-layer protocols in software. SDR technology can be used to implement military, commercial and civilian radio applications. A wide range of radio applications like Bluetooth, WLAN, GPS, Radar, WCDMA, GPRS, etc. can be implemented using SDR technology.
This paper presentation provides an overview of generic SDR features and its architecture with a special focus on the benefits it offers in commercial wireless communication domain.

The digital radio system consists of three main functional blocks: RF section, IF section and base-band section. The RE section consists of essentially analog hardware modules while IF and baseband sections contain digital hardware modules. SDR has generated tremendous interest in the wireless communication industry for the wide- ranging economic and deployment benefits it offers.
