Applications of software-defined radio (SDR) technology in hospital environments

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
A software-defined radio (SDR) is a radio communication system where the major part of its functionality is implemented by means of software in a personal computer or embedded system. Such a design paradigm has the major advantage of producing devices that can receive and transmit widely different radio protocols based solely on the software used. This

Design of analog to digital converter for SDR (Software Defined Radio)

2009 International Conference for Internet Technology and Secured Transactions, (ICITST), 2009
Software defined radio (SDR) is a potential low cost future-proofed solution to the growing number of incompatible wireless standards operating in different frequency bands and different geographical zones. The attractiveness of the concept is that the same hardware platform can be reprogrammed to operate on many different standards.

The Software-Defined Radio (SDR)

2020
Regardless of its modulation, a radio signal can be looked upon as an alternating current (AC), granted a very small one. This alternating current is therefore an analogue signal.

Special session on software defined radio (SDR) and Cognitive Radio (CR)

2010 International Conference on Embedded Computer Systems: Architectures, Modeling and Simulation, 2010
SDR is a technique where the physical layer processing of a communications modem is implemented in software. Software implementations of modems enable Cognitive Radios (CR) that can sense their environment, select interference-free frequencies, and dynamically change modulation properties.

Software defined radio (SDR) foundations, technology tradeoffs: A survey

2017 IEEE International Conference on Power, Control, Signals and Instrumentation Engineering (ICPCSI), 2017
Software radio has emerged as a focus of both academic research and commercial development for future wireless systems. This paper briefly reviews the foundation concepts of the Software Radio. It then characterizes the tradeoffs among core software-radio technologies. Object oriented analysis leads to the definition of the radio reference platform and

Multi-Mode reconfigurable Software Defined Radio architecture for avionic radios

2017 Integrated Communications, Navigation and Surveillance Conference (ICNS), 2017
This paper presents an architecture using Software Defined Radio (SDR) techniques to integrate multiple avionic radios in a single hardware module. This architecture allows avionic radio functions to share the same computational and hardware resources, run simultaneously numerous avionic radios, and dynamically reconfigure the resource allocation ...

Hands-on software defined radio experiments with the low-cost RTL-SDR dongle

2015 IEEE Signal Processing and Signal Processing Education Workshop (SP/SPE), 2015
Software defined radio (SDR) is an exciting merger of digital signal processing and wideband radio hardware. The term SDR came into more common usage in 1992 by Dr. Joe Mitola, but actually had its beginnings back in 1984 at E-Systems. The ideal SDR receiver consists of an antenna connected to an analog-to-digital converter (ADC) followed by a digital ...

Model-based software-defined radio(SDR) design using FPGA

2011 IEEE INTERNATIONAL CONFERENCE ON ELECTRO/INFORMATION TECHNOLOGY, 2011
A software-defined radio (SDR) allows for digital communication systems to easily adopt more sophisticated coding and modulation technologies, which is extremely important in meeting the ever-increasing demands of the wireless communication industry. In this study, an SDR has been constructed using Xilinx system generator tools and implemented on the ...
