The Research of Chirp Signal Based on GNU Radio and USRP

Abstract:

This paper put forward a research of the chirp signal and its generated method. The research was based on a software-defined radio (SDR) system, which was composed of GNU Radio and Universal Software Radio Peripheral (USRP). It introduced the chirp signal and design algorithm to show how to generate the chirp signal based on DDS technique. And it provided two platforms including the FPGA platform and SDR platform to generate the chirp waveforms. Finally, it analyzed the difference between the two platforms. From the waveforms using these two platforms displayed in oscilloscope, it found that the results based on SDR were better. And it demonstrated that advantages of GNU Radio and USRP.
