Software Defined Radio

This paper deals with Software Defined Radio (SDR) is a technology which makes it possible to implement the radio communication process simply with software. Comparing to the traditional radio communication systems, SDR omits all the hardware and replaces them by pure software. This solution also gives a great advantage in flexibility because a SDR receiver is able to decode all the signals. Past decades deals with many communication standards and even today also many researches are going on. A major problem in these are different communication standards use different hardware circuitry which causes these communication standards regional. Inoder to mitigate this problem, many developments are occurred in mobile communication to develop a communication system which works by swapping the software with a single hardware circuitry. The main aim of this paper is to develop a model of a Software defined Radio using MATLAB tool and to simulate the Bluetooth standard. For the Bluetooth standard the basic modulation scheme used is GFSK and Frequency hopping spread spectrum is used.
