Cyclo-stationary Spectrum Sensing Using GNU Radio

2021 2nd Global Conference for Advancement in Technology (GCAT), 2021
Spectrum shortage is a key problem as wireless communication is developing at an increasing rate. Licensed spectrum band users only use a portion of their reserved resources; thus, cognitive radios (CRs) are a necessary component to unlock the unclaimed spectrum through dynamic spectrum management.

Latency Analysis in GNU Radio/USRP-Based Software Radio Platforms

MILCOM 2013 - 2013 IEEE Military Communications Conference, 2013
Software-Defined Radio (SDR) is a promising radio technology that implements radio communication functionalities in software instead of hardware. Advantages of a SDR system are reconfigurability and flexibility whereas disadvantages are low throughput and high latency. Our research focuses on analyzing and measuring latency of a SDR system based on GNU

A GNU radio-based signal detector for cognitive radio systems

2011 IEEE International Instrumentation and Measurement Technology Conference, 2011
This paper deals with the hardware and software architecture of a signal detector prototype. It is able to observe a wide band and to find, in such band, the empty or occupied channels. It is intended to be used either in telecommunication devices or in spectrum monitoring instruments working in the new scenarios of telecommunications, where a flexible

Configure Cognitive Radio using GNU Radio and USRP

2009 3rd IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2009
Cognitive Radio (CR) is considered as a potential solution to improve spectrum utilization via opportunistic spectrum implement. Using Software defined Radio (SDR) technology, a flexible radio platform can be potentially configured a Cognitive Engine (CE) to transmit and receive many different incompatible radio standards.

Remote Triggered Software Defined Radio Using GNU Radio

2017
Software-defined radio (SDR), refers to wireless communication in which the transmitter and receiver both are able to modulate signals defined by a computer software. It is the capability of a system to behave as a transceiver and to be configured to various systems with the help data flow graphs on a software.

ATSC 3.0 implementation in GNU Radio Companion

2017 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2017
High quality television services entail more complex systems and higher costs of prototyping, development and testing methods. The concept of Software-Defined Radio, which addresses flexibility and adaptability to new systems as they are researched, is an option to study the behavior of some technologies that will be used in future systems.

Realization of Kalman filter in GNU radio

2017 International Conference on Computer Communication and Informatics (ICCCI), 2017
The paper develops a basic idea pertaining to Kalman filters. The interest in Kalman filter is motivated by the wide variety of applications it provide. The Kalman filter is an iterative filter which considers a series of measurements (that contains statistical noise) over time, and then estimates the unknown variable.

GNU radio as an experimental platform

Proceedings of the second ACM international workshop on Wireless network testbeds, experimental evaluation and characterization, 2007
In this talk, Eric Blossom, founder and maintainer of the GNU Radio project, will present an overview of the current capabilities and applications of GNU Radio. In addition, he will discuss future plans relevant to networking as well as the port of GNU Radio to the Cell Broadband Engine. 30 to 200 GFLOPS makes new things possible!

Enhancing GNU Radio with Heterogeneous Computing

Proceedings of the 2015 Workshop on Software Radio Implementation Forum, 2015
Software radio system performance can be significantly enhanced with appropriate architectural choices, such as the GNU Radio USRP's division of roles between an FPGA and a general purpose CPU. Heterogeneous architectures provide the most flexibility for achieving high computational performance; yet have not been fully exploited by today's software ...
