Watermark Detector Based on Stochastic Resonance Phenomenon

Abstract

In this work it is presented an application of the striking Stochastic Resonance phenomenon to Telecommunication field. This allows the detection of signals in very low signal-noise scenarios only if the appropriated amount of noise is added. As a result of our analysis we developed a prototype over FPGA development board which consists of a detector system of watermarks in audio signals based on Stochastic Resonance mechanism.
