On the detectability of weak signals
IEEE Trans. Inf. Theory, 2020Approximate performance results are obtained for optimal detection of weak discrete time signals. The analysis parallels the ''locally optimum'' approach for detector design and is based on a small-signal Taylor series approximation to the Chernoff error probability bounds.

Abstract The weak signal concept according to Ansoff has the aim to advance strategic early warning. It enables to predict the appearance of events in advance that are relevant for an organization. An example is to predict the appearance of a new and relevant technology for a research organization.

Weak-signal iterative holography
Applied Optics, 2015An iterative holographic table-top experiment is presented, where a recorded hologram is used to re-illuminate the initial target. With this beam shaping setup, more light is directed to the target for each iteration until a convergence limit is met. We experimentally examine convergence properties of this iterative hologram reconstruction approach for

Powerful signals for weak muscles
Ageing Research Reviews, 2009The aim of the present review is to summarise, evaluate and critique the different mechanisms involved in anabolic growth of skeletal muscle and the catabolic processes involved in cancer cachexia and sarcopenia of ageing. This is highly relevant, since they represent targets for future promising clinical investigations.

GNSS signal acquisition in weak signal condition
2014 9th International Symposium on Communication Systems, Networks & Digital Sign (CSNDSP), 2014In this paper, a new method for Global Navigation Satellite System (GNSS) signal acquisition in weak signal condition is considered, mainly on bit transition and accumulation over multiple code periods. The impact of bit transition on the acquisition block is analyzed and an algorithm based on the Discrete Fourier Transform (DFT) operation is proposed ...

Detection of multi-frequency weak signals with adaptive stochastic resonance system
Chinese Journal of Physics, 2018Aiming at the poor detection rate of multi-frequency weak signals under a strong background of noise, a novel method based on adaptive stochastic resonance (SR) theory is proposed in this paper.

We consider the distributed detection of weak signals from one-bit measurements collected by a sensor network where observation model uncertainties exist at all the sensor nodes. To solve this problem, a one-bit locally most powerful test (LMPT) detector
