At the “Information exchange and Technology Platform Seminar” held on December 26, 2009 at STM, Teoman Sadan PASINLIOGLU from the Systems Department delivered a presentation on “Digital Radios”.

In the presentation, it was pointed out that software-based radio is an approach that has been widely discussed in the recent years and that envisages to maximize the software-based realization rate of radio functions. 

Saying that the level of technology reached in software-based radio with regard to analogue/digital and digital/analogue converters currently only allows software control at the main band and the IF band, PASINLIOGLU said that the analogue-to-digital conversion rate at the RF level is not at the desired level and that the software radio implies the latest conceptual point achievable in software-based radios. 

PASINLIOGLU explained that under the said conceptual model, the electrical signal acquired via the antenna is digitalized as soon as it is amplified, and therefore executed as a software in a fully-digital environment at the IF and main band layers following the signal flow. Saying that this means that all radio functions other than the antenna can be executed under software control, PASINLIOGLU added that today’s technology has not yet reached this level and that it is expected that this conceptual target will be very close in the coming years.

The seminars have been organized on the Saturday of the last week of every month for the last two years, with the participation of employees from the relevant departments of the company.
