It is shown that, for the CDMA spread spectrum signal described in the paper, it is still possible to positively detect the presence of a watermark without being able to decode it

In this context, we develop signal processing tools based on Split Spectrum Processing (SSP) with Q constant method allowing to detect and locate the imperfections present in

De plus, pour ces composés 5b-d, on observe la présence d’une phase cristal liquide smectique pour laquelle les molécules ne possèdent plus d’ordre de position au sein des

Le produit brut est purifié par chromatographie sur silice flash (hexane/toluène 9 : 1) suivi d’une recristallisation à partir d’un mélange méthanol/toluène pour obtenir un

The first three main purposes of our application are 1) to enable non-specialists to identify a watermark using a simple photograph by searching for a potential matching watermark

The underWater AcousTic channEl Replay benchMARK (Watermark) is a realistic simulation tool now made available to the underwater communications community.. It is a shell around

The BCH 1 dataset, provided by Telecom Bretagne, contains four time-varying channel impulse responses (TVIR) measured in the commercial harbor of Brest (France) in the frequency
