Picture this scenario: You have a problem with your SDR’s performance and your hardware engineer starts by pointing fingers at the software. No doubt, the software engineers in turn blame the hardware. This isn’t a case of hardware and software engineers being mistrustful of each other. It’s just a reflection of the difficulty in isolating the cause of performance problems.
How does your organisation deal with this situation?
We’ve asked SDR system architects and project managers about the challenges they face in SDR design and development, and one of the questions we heard was:
Given that much of SDR’s physical layer is implemented in software, how do you integrate a robust test environment into the design process that takes into account the fact that many of the problems assumed to be hardware related could be software problems or even software-hardware interaction problems?
Join us as we delve deep into the challenges of SDR and Cognitive Radio design and explore the role test has to play in bringing your SDR products to market in time and on budget. A number of real-life design problems are covered in detail giving you fresh insight into mitigating design and certification risk.
Bob Cutler is a lead technologist within Agilent's Technology Leadership Organization (TLO) He is a co-inventor of Vector Signal Analyzers (VSA's), and has been involved the development of modulation analysis techniques and other measurement algorithms for a wide variety of digital RF communications formats, with an emphasis on new and emerging technologies. More recently Bob has been developing RF sensor networks for signal detection and TDOA-based geolocation algorithms. As a measurement and technology expert, Bob has also actively contributed to the creation of RF test procedures incorporated into various IEEE and ETSI standards, and is currently Agilent's technical representative to the SDR Forum.
