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.

Meteorological picture reception system using software defined radio (SDR)

2017 IEEE Second Ecuador Technical Chapters Meeting (ETCM), 2017
In this paper is shown the development of a low cost prototype that allows the visualization of meteorological images though the acquisition and the processing of a signal in Automatic Picture Transmission (APT) format, which is transmitted by National Oceanic and Atmospheric Administration (NOAA) polar orbit satellites. The deployment of the system is

DSB-SC AM based software defined radio(SDR) design

2016 IEEE International Conference on Recent Trends in Electronics, Information & Communication Technology (RTEICT), 2016
The rapid growth in speed and density of programmable logic devices such as FPGA's (Field Programmable Gate Arrays) facilitates ever more complex designs to be built within a short time frame. The adjustability of a programmable device makes it easy to integrate a design with variety of peripherals or components on a single chip and makes it versatile.

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 ...

Antenna design strategy and demonstration for software-defined radio (SDR)

Analog Integrated Circuits and Signal Processing, 2011
Antennas are a key enabling technology for software-defined radio (SDR). Although software is extremely flexible, SDR's potential is limited by antenna size and performance. In this paper, we review typical antenna miniaturization techniques and fundamental theories that limit antenna size and performance including operational bandwidth, gain (or range)

Implementation of ADS-B receiver using software define radio (SDR)

AIP Conference Proceedings, 2021
The next satellite development plan in the satellite technology center, LAPAN is a constellation satellite where one of the payloads to be carried is Automatic Dependant A Surveillance-Broadcast (ADS-B). This payload is an observation technology applied to air transportation for air traffic control based on GPS technology from satellites.

Software defined radios (SDR) platform and application programming interfaces (API)

2001 MILCOM Proceedings Communications for Network-Centric Operations: Creating the Information Force (Cat. No.01CH37277), 2002
A software defined radio, as defined by the Federal Communications Commission (FCC) Notice of Proposed Rule Making (NPRM), FCC 00-430, is fully software driven and performs all digital signal processing using programmable digital signal processors, general purpose microprocessors, or field programmable gate arrays.

Multirate Digital Signal Processing for Software Defined Radio (SDR) Technology

2008 First International Conference on Emerging Trends in Engineering and Technology, 2008
In the past, radio systems were designed to communicate using one or two wave forms. As a result, two groups of people with different types of traditional radio were not able to communicate due to incompatibility. The need to communicate with people using different types of equipment can only be solved by using software defined radio (SDR).

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) architecture to support multi-satellite communications

2015 IEEE Aerospace Conference, 2015
Software Defined Radio (SDR) is a key area to realise new software implementations for adaptive and reconfigurable communication systems without changing any hardware device or feature. A review on efficient use of limited bandwidth and increasing distributed satellite missions can lead to the need for a generic yet configurable communication platform ...
