Signal Structure of the Starlink Ku-Band Downlink
Todd E. Humphreys, Peter A. Iannucci, Zacharias Komodromos +1
We develop a technique for blind signal identification of the Starlink downlink signal in the 10.7 to 12.7 GHz band and present a detailed picture of the signal's structure. Import…
Downlink Analysis of LEO Multi-Beam Satellite Communication in Shadowed Rician Channels
Eunsun Kim, Ian P. Roberts, Peter A. Iannucci +1
The coming extension of cellular technology to base-stations in low-earth orbit (LEO) requires a fresh look at terrestrial 3GPP channel models. Relative to such models, sky-to-grou…
All-Weather sub-50-cm Radar-Inertial Positioning
Lakshay Narula, Peter A. Iannucci, Todd E. Humphreys
Deployment of automated ground vehicles beyond the confines of sunny and dry climes will require sub-lane-level positioning techniques based on radio waves rather than near-visible…
Fused Low-Earth-Orbit GNSS
Peter A. Iannucci, Todd E. Humphreys
Traditional Global Navigation Satellite System (GNSS) immunity to interference may be approaching a practical performance ceiling. Greater gains are possible outside traditional GN…
First results from three years of GNSS Interference Monitoring from Low Earth Orbit
Matthew J. Murrian, Lakshay Narula, Peter A. Iannucci +4
Observation of terrestrial GNSS interference (jamming and spoofing) from low-earth orbit (LEO) is a uniquely effective technique for characterizing the scope, strength, and structu…
Automotive-Radar-Based 50-cm Urban Positioning
Lakshay Narula, Peter A. Iannucci, Todd E. Humphreys
Deployment of automated ground vehicles (AGVs) beyond the confines of sunny and dry climes will require sub-lane-level positioning techniques based on radio waves rather than near-…
Automotive Collision Risk Estimation Under Cooperative Sensing
Daniel LaChapelle, Todd Humphreys, Lakshay Narula +2
This paper offers a technique for estimating collision risk for automated ground vehicles engaged in cooperative sensing. The technique allows quantification of (i) risk reduced du…
De-randomizing Shannon: The Design and Analysis of a Capacity-Achieving Rateless Code
Hari Balakrishnan, Peter Iannucci, Jonathan Perry +1
This paper presents an analysis of spinal codes, a class of rateless codes proposed recently. We prove that spinal codes achieve Shannon capacity for the binary symmetric channel (…
A Brief Introduction to Band Structure in Three Dimensions
Peter Iannucci
Without our ability to model and manipulate the band structure of semiconducting materials, the modern digital computer would be impractically large, hot, and expensive. In the und…
