Spinal codes are a new class of rateless codes that enable wireless networks to cope with
time-varying channel conditions in a natural way, without requiring any explicit bit rate …

In addition to Internet service, new commercial broadband low-Earth-orbiting (LEO)
satellites could provide a positioning, navigation, and timing (PNT) service far more robust to …

Traditional Global Navigation Satellite System (GNSS) immunity to interference may be
approaching a practical performance ceiling. Greater gains are possible outside traditional …

This paper analyzes the precision bounds of ranging (via time-of-arrival estimation) with
OFDM signals and proposes methods for the co-design of OFDM waveforms meeting both …

In this article, 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. …

Observation of terrestrial GNSS interference (jamming and spoofing) from low Earth orbit (LEO)
is a uniquely effective technique for characterizing the scope, strength, and structure of …

Recently, rateless codes have introduced a promising approach to obtaining wireless throughput
higher than what is achieved by fixed-rate codes, especially over time-varying channels…

One way that software-defined radio (SDR) receivers for Global Navigation Satellite Systems
(GNSS) differ from traditional GNSS receivers is that radio-frequency (RF) data serialization …

A system is presented for multi-antenna carrier phase differential GNSS (CDGNSS)-based
pose (position and orientation) estimation aided by monocular visual measurements and a …

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…
