  • COGNITIVE RADIO WIRELESS COMMUNICATION LAB CRL04

    Description:

    A cognitive radio is an intelligent radio that can be programmed and configured dynamically. Its transceiver is designed to use the best wireless channels in its vicinity. Such a radio automatically detects available channels in wireless spectrum, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given spectrum band at one location. This process is a form of dynamic spectrum management. The burden on faculty is lowered by using courseware designed at IITD. Lab technicians are eased by integrated hardware and software from same source for trouble free performance.

    The system is ideally suited for applications requiring high RF performance and great bandwidth such as physical layer prototyping, dynamic spectrum access and cognitive radio, spectrum monitoring and even networked sensor deployment.

    The Superspeed USB 3.0 interface at 5Gbps serves as the connection between the transceivers and the mobile workstation. This enables the user to realize 40 MS/s of real- time bandwidth in the receive and transmit directions, simultaneously (full duplex). FPGA is autoloading so hardware is plug and play as a pen drive! No need to program the FPGA for most cases!
