ononicsThis report contains basic information on Cognitive Radio and SoftwareDefined Radio. Software Defined Radio is an emerging technique in thisdomain that promises easy portability and adaptability of newtechniques on the same hardware. Cognitive Radio technique utilizesthis Software Defined Radio to intelligently and efficiently utilize theavailable frequency spectrum knowing about the side information of other users sharing the same spectrum.The report talks about the Cognitive Radio technique and goes intodetails of its Software implementation (on Simulink and MATLAB) usingSpectrum Sensing and the practicality of cognitive radio in our presentscenario of communication and its actual hardware implementation onSoftware Defined Radio.
1.1 Introduction to Software-Defined Radio With the exponential growth in the ways and means by which people need tocommunicate - data communications, voice communications, videocommunications, broadcast messaging, command and control communications,emergency response communications, etc. - modifying radio devices easily and cost-effectively has become business critical. Software defined radio (SDR) technologybrings the flexibility, cost efficiency and power to drive communications forward,with wide-reaching benefits realized by service providers and product developersthrough to end users.Simply put Software Defined Radio is defined as:
"Radio in which some or all of the physical layer functions are software defined" Software-Defined Radio (SDR) refers to the technology wherein software modulesrunning on a generic hardware platform consisting of DSPs and general purposemicroprocessors are used to implement radio functions such as generation of transmitted signal (modulation) at transmitter and tuning/detection of receivedradio signal (demodulation) at receiver.SDR technology can be used to implement military, commercial and civilian radioapplications. A wide range of radio applications like Bluetooth, WLAN, GPS,
