Software-Defined Radio

Software-defined radio is a very promising technology and has been so for at least a decade now. Today it is taking the step from promise to delivery. The presentations will tackle the biggest challenges in implementing both the kernel functionality and the radio interface.

Presentations will be made by:

“Requirements and Challenges for the Hardware Implementation of Software Defined Radio”

Abstract. Next generation radio systems need to manage many different frequency bands and many different radio standards (with different bandwidths, modulation formats and protocols). Software defined radio is a key technology to achieve this with limited cost, power consumption and form factor. Some of the challenges in designing software defined radios have solutions, but some are left. We have identified maybe the biggest challenges, how to handle strong blockers by the analog part of the receiver chain, how to manage programmable digital signal processing at low power, and how to design a transmitter power amplifier. The talk will concentrate on these challenges and discuss possible technical solutions.

Biography.
Christer Svensson received the M.S. and Ph.D. degrees from Chalmers University of Technology, Gothenburg, Sweden, in 1965 and 1970, respectively. He was with Chalmers University from 1965 to 1978, where he performed research on MOS transistors, nonvolatile memories, and gas sensors. He joined Linköping University, Sweden 1978, where he became Professor in Electronic Devices 1983 and initiated a new research group on integrated circuit design. He pioneered the fields of high-speed CMOS design in 1987, and low-power CMOS 1993. His present interests are high performance and low power analog and digital CMOS circuit techniques for computing, wireless systems and sensors. He founded several companies, for example, Switchcore (publ.) and Coresonic where he also serves as director. He is a member of the Royal Swedish Academy of Sciences, the Royal Swedish Academy of Engineering Sciences and was 2003 awarded Fellow of IEEE.

”Requirements and Challenges for the Hardware Implementation of Software Defined Radio”

With the rapid development of wireless technology, the industry has been challenged to discover faster and more productive ways to develop and test communication systems. A software-defined radio system is a design in which certain hardware components are implemented in software. Because these components are defined in software, you can adjust a software-defined radio system as needed without making significant hardware changes. This presentation introduce the concept of the software defined radios and how to minimize the time to market by using FPGA based hardware for prototyping these radios.
