Rain Rate Estimation Bounds and Weather-Adaptive Pilot Allocation for LEO Satellite ISAC
Haofan Dong, Houtianfu Wang, Hanlin Cai +2
Rain attenuates Ku-band satellite signals by up to 20~dB, encoding precipitation information along the Earth-space slant path. This paper derives the Bayesian Cramér-Rao bound (BCR…
CisLunarSense: Opportunistic ISAC for Debris Detection at the Lunar Gateway
Haofan Dong, Ozgur B. Akan
We propose CisLunarSense, an opportunistic integrated sensing and communication (ISAC) framework that exploits the Lunar Gateway's Ka-band relay for monostatic debris detection, ad…
Fisher Information Limits of Satellite RF Fingerprint Identifiability for Authentication
Haofan Dong, Ozgur B. Akan
RF fingerprinting authenticates satellite transmitters by exploiting hardware-specific signal impairments, yet existing methods operate without theoretical performance guarantees.…
Performance Bounds and Robust Filtering for LEO Inter-Satellite Synchronization under Cross-Epoch Doppler Coupling
Haofan Dong, Houtianfu Wang, Hanlin Cai +1
Low Earth orbit (LEO) inter-satellite links (ISLs) must achieve joint synchronization and ranging under severe hardware impairments, namely oscillator phase noise, clock drift, and…
Distortion Is Not Noise: On the Limits of the Kappa Model for Monostatic ISAC
Haofan Dong, Ozgur B. Akan
Monostatic ISAC sensing differs from communication because the transmitter can monitor its distorted transmit waveform. Thus, the aggregate distortion model, which treats impai…
Cramer--Rao Bounds for Magneto-Inductive Integrated Sensing and Communications
Haofan Dong, Ozgur B. Akan
Magnetic induction (MI) enables communication in RF-denied environments (underground, underwater, in-body), where the medium conductivity imprints a deterministic signature on the…
