08.30 - 11.00Workshop A: Definition of a complete software radio standard

For nearly ten years now the Software Communications Architecture (SCA) has dominated the international effort to describe a standardized software radio. Given this level of maturity it is now clearly understood what SCA is and is not. A little over two years ago a set of Application Program Interfaces (API's) were published by the US JTRS program in an attempt to fill in the gaps not covered by the SCA. As ESSOR is now on a timeline to produce API's and an architecture in the mid-2010 time frame what work remains to be done in definition of a complete software radio standard?

This workshop firstly examines the software radio standards as they exist today. This analysis covers the SCA, the POSIX AEP, CORBA, and CORBA-based services. What follows is a thorough view of the JTRS API's. Finally this workshop concludes with a discussion of the items that remain to be defined in order to complete a standardized description of the software radio.

11.15 - 13.45Workshop B: SDR – Challenges and Solutions in RF front-End Design (Challenges and Solutions in RF front-End Design for SDR)

The vision of a frequency-agile and hardware efficient SDR has attracted much attention but as such it has not become a real product yet. The contemporary multi-standard radio used in mobile communications is based on multiple RF filters or even multiple RF front-ends are used to serve individual frequency bands. Including traditional receiver architectures with inflexible RF filters and A/D conversion at IF or baseband, these solutions are far from the original SDR vision, still challenging researchers and RF engineers.

Following this vision we will discuss design concepts and present experimental results which pave the way for mature implementation of the SDR front-end in the future. We will begin from characterizing the radio paradigm to better understand the requirements and drawbacks for SDR in terms of a realistic RF environment and the available technology. The key limitations due to noise, interference, nonlinear distortions and power consumption will be discussed in detail and illustrated by practical examples. The design challenges both for receiver and transmitter part will be addressed with the emphasis on filtering, frequency conversion and digitization.

The workshop is planned to include expertise from the audience in an interactive format.
