Distributed detection of narrowband signals
IEEE Transactions on Information Theory, 1995Summary: Distributed signal detection schemes have recently received significant attention, but most research has focused on cases with independent observations at the different sensors. Cases with dependent narrowband signals, which are of practical interest in communication, radar, and sonar problems, are studied here.

Proceedings of 1995 IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications (Conjunction with INTER COMM'95), 2002
The uniform distribution of signal energy achieved by simulcast improves wide area reception reliability, but it also introduces additional sources of destructive interference. Our laboratory and field experiments show that simulcast is analogous to multipath with transmitter frequency offsets being equivalent to Doppler shift, and differential ...

Sensitive detection of narrowband pulses
Acta Astronautica, 1986Highly monochromatic signals, such as TV carriers, can be detected sensitively by using a narrow filter (b < or = 1 Hz) and performing power accumulation on its output. If instead a low-duty-cycle pulsed signal of the same total energy is present, the sensitivity of a square law device, followed by a thresholding operation (to eliminate most samples

Hearing studies show that zebra finches, Taeniopygia guttata, small song birds that produce broadband, harmonic vocalizations are unusually sensitive to the mistuning of a single component in a harmonic complex [Lohr and Dooling, J. Comput. Psychol. 112, 36–47 (1998)].

Narrowband Ultraviolet Vapor Filter
Applied Optics, 1975A narrowband optical vapor filter based on the principle of selective specular reflection from vapors is described. The device consists of a mercury vapor cell with Brewster angle windows that selectively reflects the 2537-A line and transmits other radiation.

Ocean 72 - IEEE International Conference on Engineering in the Ocean Environment, 1972
A narrowband HF-SSB system designed to meet the requirements recommended by the Joint WMO/IOC group of experts on telecommunications for oceanographic data and command telemetry transmissions is described. The building blocks that compose this ocean data buoy HF telemetry system, and their more important characteristics, are listed.

Computor Simulation of Narrowband Systems
IEEE Transactions on Computers, 1968Abstract—Any narrowband signal can be represented by two low-frequency functions, containing only frequencies lower than the bandwidth, which represent the envelopes of the in-phase (cosine) and quadrature ( sine) components of the carrier frequency. To obtain the transient response of a narrowband system efficiently by computer simulation, the system ...

Narrowband : the decline of telecommunications in Italy
Economia dei Servizi, 2014Italy has been at the forefront of the telecommunication and IT industries. However, in the last decades, its competitive advantage has been rapidly fading out. When it comes to IT literacy, diffusion of Internet, TLC infrastructures, Italy is often among the worst performing countries in Europe.

The "narrowband" assumption is often made in the analysis of array signal processing algorithms. The author provides a definition for the notion of narrowband, and the derivation of an expression which is useful in determining if a particular scenario qualifies as narrowband.
