Session Abstract

"Matt Ettus, GNU Radio team member and Universal Software Radio Peripheral (USRP) creator, will be discussing both the technical and regulatory aspects of open source software radio, and how GNU Radio and the USRP fit in. He will also cover software radio's impact on spectrum policy, and will conclude with a small demo of the USRP.

In a software radio, software defines the transmitted waveforms, and software demodulates the received waveforms. GNU Radio is an open source software radio framework which allows for experimentation, rapid prototyping and deployment of complex Software Radio systems on generic microprocessors. Software radio is becoming increasingly important as a technology for implementing communication systems. By performing most or all processing in software, it allows for extremely versatile radio systems and makes multi-standard systems possible.

The Universal Software Radio Peripheral (USRP) is a hardware component which allows for the physical realization of complex wideband software radios using commodity PCs. It allows for up to 4 antennas, enabling MIMO and Smart Antenna systems. The hardware design is completely open and free."
