Mobile Communication Signal Selection Algorithm for Signal of Opportunity Navigation
2021 23rd International Conference on Advanced Communication Technology (ICACT), 2021At present, the satellite navigation and positioning system can provide a high precision positioning service to end users in outdoor environments. But in urban canyons, high-rise buildings, urban tunnels, tree canopy covered areas, and other environments with weak signal such as military base and other special places with signal disturbance or spoofery,

Passive radar via LTE signals of opportunity
2014 IEEE International Conference on Communications Workshops (ICC), 2014Passive radars relying on signals of opportunity enable new applications based on stealth tracking of targets without the need of radar signals emissions. Long term evolution (LTE) base stations employing orthogonal frequency division multiplexing (OFDM) signals are excellent candidates as illuminators of opportunity thanks to their wide availability ...

Modeling the Coherence of Scattered Signals of Opportunity
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019The reflection of radar echoes collected under both monostatic and bistatic configurations generally undergoes losses of coherence. These can be affected by many factors, depending on both the system features and the illuminated surface, and it should be properly considered for an accurate characterization of the scattering phenomenon.

Signals of Opportunity Aided Inertial Navigation
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2016A signal of opportunity (SOP)-aided inertial navigation system (INS) framework provides various technical solutions to technical problems facing GNSS implementations. A mobile receiver, whether handheld or vehicle-mounted, has access to Global Navigation Satellite System (GNSS) signals, multiple unknown terrestrial SOPs, and IMU measurements, which are
