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.
