    COGNITIVE RADIO AND SDR BASED DESIGN OF DIGITAL MODULATORS AND DEMODULATORS USING GNU RADIO TOOL
    Sayali P Pandit*, Soni Chaturvedi

    There has been a great increase in the use of wireless communication since a decade. The development of many new devices has lead to a conflict of the application of available resources to perform the communication with efficiency. To have control over these problems and for the proper usage of the available spectrum the concept of cognitive radio is used and developments are made in order to counter the existing problems. Cognitive radio helps in proper spectrum management and allows the secondary user to utilize the white spaces without hindering the primary user. Software defined radio platform helps in controlling and reconfiguration of the parameters according to the environment. SDR helps in reconfiguring the secondary user to allow it to establish itself in the environment. Cognitive radio is the future of wireless communication where the advances in the use of new communication devices and increased number of users can be handled more effectively by using SDR than the conventional radio.
