Abstract

This lecture will begin with the definition, history and evolution of Software Defined Radio (SDR). RF/microwave engineers will find it clear and understandable because analogies will be made to conventional classic radio systems and components. The lecture will then introduce the concepts of oversampling and undersampling as it applies to SDR. There will be an introduction to the details of correctly driving and implementing an A/D converter as this is one of the important areas that the RF/microwave engineer will be asked to do. There will be an introduction and explanation of the firmware and software portions of SDR and a comparison with state-of-the art conventional analog circuitry will be shown. A live demonstration of SDR will be presented. Software Defined Radio (SDR) is the culmination of advances on several fronts and probably the most significant area of development in radio systems today.

 

Biography

Dr. Jeffrey Pawlan (M 1989, SM 1996) has been a consultant as owner of Pawlan Communications for 25 years. Prior to that, he had worked for many companies in California in very diverse areas of analog, RF, and microwave design and has been an engineer for 40 years. Some of his work was for NASA projects including the very successful design of the SARSAT/COSPAS search and rescue satellite ground stations. He also taught engineering part-time.
