Abstract
Global Positioning System (GPS) signals in the L1 band are inherently vulnerable to both intentional and unintentional jamming because of their low received power levels. In this study, the performance of three different adaptive filtering algorithms is investigated against five representative jammer types in a GPS L1 receiver employing a single-element patch antenna. The considered jammer types include continuous-wave, swept, pulsed, wideband, and Binary Phase Shift Keying (BPSK)-modulated interference. The evaluated algorithms comprise the Least Mean Squares (LMS), Recursive Least Squares (RLS), and Adaptive Notch Filter-based approaches. Simulation-based assessments are carried out in terms of signal-to-noise-and-interference ratio improvement, bit error rate, convergence speed, and computational complexity. The results indicate that each algorithm offers distinct performance advantages depending on the characteristics of the interfering signal.
The 2483.5-2500 MHz S-band has gained increasing attention as a candidate frequency for Regional Navigation Satellite Systems (RNSS), such as Navigation with Indian Constellation (NavIC) and South Korea's Korean Positioning System (KPS). However, this band is adjacent to terrestrial services such as the Long-Term Evolu...

This paper considers a hybrid frequency- and phase-shift keying (FPK) waveform for integrated sensing and communications (ISAC). Compared to FSK-based ISAC waveforms in the literature, the proposed waveform shows similar local radar estimation accuracy and superior performance both in terms of data rates and radar glob...
