Active duplexing for Software Defined Radio
2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014Passive filters are implemented via advanced technologies in the form of surface acoustic wave (SAW) and thin film bulk acoustic resonator (FBAR) devices. These not only exhibit low noise and high linearity features, but also have fixed centre frequency and bandwidth, making them inflexible.

Advances in software defined radio
Annales Des Télécommunications, 2002Progress in software defined radio has been rapid, since the term was first coined in the mid 1990s. In this brief overview we summarise some of the recent advances in software defined radio from a range of technology perspectives — radio frequency design, baseband reconfigurability, reconfigurable applications and protocols and regulatory (and related

Software Defined Radio for Communications
2018 IEEE Frontiers in Education Conference (FIE), 2018Software Defined Radio (SDR) has evolved in the past decade from a topic that was only briefly mentioned in passing in graduate special topics courses to one that is now accessible to students at all levels. The rapid proliferation of cost effective SDR hardware has allowed not only the development of undergraduate SDR communication labs, but ...

Tamper Resistance for Software Defined Radio Software
2009 33rd Annual IEEE International Computer Software and Applications Conference, 2009The security of software defined radio (SDR) software is essential to the trustworthiness of the overall radio system. When designing and developing security solutions for SDR software, its performance requirements, such as stringent real-time constraint, need to be considered.

Hacking Satellites With Software Defined Radio
2020 AIAA/IEEE 39th Digital Avionics Systems Conference (DASC), 2020The race to put satellites into space has attracted new commercial players and amateur satellite operators. Even though these satellites rise level of new innovations and services for consumers, lack of regulations and standards consequently brings solutions which are not so well protected.

Tutorial: Software-defined radio technology
2007 25th International Conference on Computer Design, 2007Software defined radio (SDR) is one of the most important emerging disruptive technologies that shaped wireless communication and mobile computing industries. The "ideal" software radio consists of a wideband antenna, wideband ADC and DAC, and a programmable processor.

MILCOM 2005 - 2005 IEEE Military Communications Conference, 2006
Software defined radio (SDR) is a new approach for military radio systems. This new radio paradigm supports multiple channels with simultaneous waveforms, providing a new level of scalability and flexibility to the user, and allows for rapid technology insertion as it becomes available.

Software defined radios for small satellites
2014 NASA/ESA Conference on Adaptive Hardware and Systems (AHS), 2014Clusters, constellations, formations, or `swarms' of small satellites are fast becoming a way to perform scientific and technological missions more affordably. As objectives of these missions become more ambitious, there are still problems in increasing the number of communication windows, supporting multiple signals, and increasing data rates over ...

2008 International Conference on Signals and Electronic Systems, 2008
Summary form only given. Looking through my word processor files I found that I have authored 15 papers and numerous PowerPoint presentations and tutorials that include the words software defined radio or SDR somewhere in the title. One would think that I would have some understanding of what is a software defined radio.

A programmable platform for software-defined radio
Proceedings. 2003 International Symposium on System-on-Chip (IEEE Cat. No.03EX748), 2004Integrated circuits for communication systems are usually designed with the primary goal of minimizing silicon area and power consumption. Usually, this yields a solution where each functional block in the algorithm is mapped directly into a dedicated hardware block.
