Signals and Modulation

Course Date

MONDAY, OCTOBER 20TH

Speaker(s)

Dr. Stephen Horan, Professor emeritus at New Mexico State University

Course Description

This course is directed towards personnel with limited experience in digital communications and modulation schemes. The course examines the relationships between the elements engineers use to send data from its source to its destination over a radio link. The class begins with how designers represent and sample the signals. Next, we will examine how the modulation and demodulation techniques preserve the signal’s integrity, including signal bandwidth representations, system noise estimations, and data link imperfections that will affect the end-to-end link performance. Finally, we will look at RF safety and systems-level concerns for the designer to address data system requirements, transmission regulations and constraints, and end-to-end analysis and planning.
