Performance Benchmarking Software-Defined Radio Frameworks: GNURadio and CRTSv.2
In this thesis, we benchmark the Cognitive Radios Test System version 2.0 (CRTSv.2) to analyze its software performance with respect to its internal structure and design choices. With the help of system monitoring and profiling tools, CRTSv.2 is tested to quantitatively evaluate its features and …

Design, Implementation and Assessment of BPSK and QPSK PAPR over OFDM signals using LimeSDR
… signals. A personal computer was used to host GnuRadio-based prototypes on which an OFDM system was developed using OFDM blocks inbuilt in the software. LimeSDR hardware was used to sample radio waves. A LimeSDR block was implemented in GnuRadio to interconnect with the LimeSDR module. An OFDM …

Implementation of Real-Time Software Receiver for Gps or Glonass L1 Signals
… prerequisites for the software receiver are GNUradio and QT4.0. GNUradio is an open source program which provides the driver for the USRP board. The current version used by the software receiver is GNUradio-3.1.3. The user interface program is developed by using the classes provided by QT4.0. …

SoftCast : exposing a waveform interface to the wireless channel for scalable video broadcast
… I implement SoftCast and RawPHY using the GNURadio software and the USRP platform. Results from a 20-node testbed show that SoftCast improves the average video quality (i.e., PSNR) across diverse broadcast receivers in our testbed by up to 5.5 dB in comparison to conventional single- or …

Machine Learning and Spectrum Sensing Cognitive Radio for Satcom Interference Detection
<p>Satellite communications can be interfered from intentional or unintentional sources, which causes the degradation of their communication links. This interference further leads to a reduction of data passed through the communication link and reduction of access times. Due to these risks, the …
