T-5 (ED-208): SiriusXM Satellite Radio: A Technological Overview, Carl Scarpa, SiriusXM Radio

Abstract: This talk is a general overview of how the SiriusXM satellite system works.
The talk will cover an historical overview of the origin of satellite radio and will discuss SiriusXM satellites constellations, design features, coverage capabilities, and how the satellite system is augmented with a complementary ground repeater network. The talk will outline the frequency planning of both the Sirius and XM network, the many forms of diversity that greatly improves signal reception, and the many challenges associated with robust reception of mobile satellite data. The talk concludes with an overview of the latest Generation receiver ASIC, its design process and requirements. Time permitting a demonstration of a live RF capture processing the SiriusXM signals will be shown.
