Optimizing the correlation properties of spreading codes is critical for minimizing inter-
channel interference in satellite navigation systems. By improving the codes' correlation …

Beginning launches in 2026, the GPS IIIF satellite series will be the first GPS satellites to
have a fully reprogrammable signal payload. This upcoming signal capability allows for the …

Binary spreading codes with good auto-and cross-correlation properties are critical for
satellite navigation to ensuring precise synchronization and tracking with minimal inter …

In this study, we design novel approximately mutually unbiased bases (AMUBs) sequences
with arbitrary lengths and large family sizes for massive connection systems. Sequences …

In this work, we propose a method for optimizing the auto-and cross-correlation properties of
binary spreading codes while ensuring robustness to the Doppler shift effects induced by …

We propose a bit-flip descent method for optimizing binary spreading codes with large family
sizes and long lengths, addressing the challenges of large-scale code design in GNSS and …

In this paper, we extend the coverage of code division multiple access (CDMA) using
simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STARRIS) …

Today, billions of users rely on GPS on a daily basis. Woven into the fabric of modern
civilization, GPS underlies nearly every aspect of society's functions, including our …
