An Introduction to Software Defined Radio (SDR)

Software Defined Radio (SDR) is the culmination of advances on several fronts, and is probably the most significant area of development in radio systems today. The entire worldwide cellular system uses SDR, NASA and the US military communications are now almost exclusively using SDR, and soon new automobile radios will use SDR to accommodate multiple modulation formats.
This talk will make SDR a clear and understandable topic based on analogies to conventional classic radio systems and components. It will introduce the concepts of (1) oversampling and undersampling as it applies to SDR, (2) correctly driving and implementing an A/D converter, and (3) the firmware and software portions of SDR.

A comparison with state-of-the art conventional analog circuitry will be presented, along with a live demonstration of SDR.

Dr. Jeffrey Pawlan, IEEE Distinguished Microwave Lecturer 2013-2015, has been a consultant at Pawlan Communications for 25 years, and has worked for numerous companies in diverse areas of analog, RF and microwave design for over 40 years.

Jeffrey has been designing RF and microwave hardware for SDR uses within instrumentation and military satellite communications since 1984, and has been working on his own hardware and software designs for the past 9 years.

In addition to his primary involvement with the IEEE Microware Theory and Techniques (MTT) Society, he is also a member of the UFFC (frequency control) concentrating on low phase noise oscillators and phase noise measurements, of the AP-S, and of the IEEE Communications Society. He has presented over 38 lectures world-wide, has taught engineering classes, has published several papers and is an inventor of two patents.
