Navigation by inertial device and signals of opportunity
Signal Processing, 2017Inertial navigation systems are known to yield rather accurate measurements over short time intervals, while their error variance tends to increase with time. In order to keep the error within specification most systems use GPS signals. In the absence of GPS data, due to jamming or spoofing, it is desirable to use signals of opportunity instead.

Signaling, Investment Opportunities, and Dividend Announcements
Review of Financial Studies, 1995This article examines potential explanations for the wealth effects surrounding dividend change announcements. We find that new information concerning managers' investment policies is not revealed at the time of the dividend announcement. We also find that dividend increases (decreases) are associated with subsequent significant increases (decreases ...

Topological Localization Via Signals of Opportunity
IEEE Transactions on Signal Processing, 2012We consider problems of localization, disambiguation, and mapping in a domain filled with signals-of-opportunity generated by transmitters. One or more (static or mobile) receivers utilize these signals and from them characterize the domain, localize, disambiguate, etc.

Hypoxia signaling: Challenges and opportunities for cancer therapy
Seminars in Cancer Biology, 2022Hypoxia is arguably the first recognized cancer microenvironment hallmark and affects virtually all cellular populations present in tumors. During the past decades the complex adaptive cellular responses to oxygen deprivation have been largely elucidated, raising hope for new anti cancer agents.

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 ...

Pervasive broadband: opportunities for signal processing
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003Summary form only given. With the emergence of broadband telecommunications, we are moving in well-measured steps from nearly universal telephony to increasingly pervasive multimedia services. The author describes some of the fundamental opportunities that this context presents to the practitioners of advanced signal processing.

Spectrum opportunity detection with weak and correlated signals
2012 Conference Record of the Forty Sixth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2012We present a novel score detector for temporal spectrum opportunity detection in cognitive radio by exploiting the differences in both energy and correlation of the empty band and the occupied band. Motivated by the challenge of detecting a weak primary user's signal without precise knowledge of the signal, where the conventional energy detector faces ...

Ocean altimetry using wideband signals of opportunity
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017Coastal altimetry plays a prominent role in measuring the total water-level envelope directly, and is one of the key measurements required by storm surge applications and services. It can also provide important information about the wave field, leading to development of more realistic wave models and therefore improving forecasts of wave setup and ...

Signal to symbol converters: Overview, opportunities and challenges
2013 47th Annual Conference on Information Sciences and Systems (CISS), 2013Signal to symbol converters (SSCs) are an emerging class of integrated microsystems aimed at an informed and intelligent conversion of signals to symbols. We present an architecture overview for signal to symbol converters, discuss related prior work and outline future opportunities and challenges.
