Summary:
Stochastic resonance (SR) is a nonlinear phenomenon in which increasing the noise intensity of a system improves the responses of that system. Traditionally, noise has been considered as a nuisance in terms of engineering applications and significant efforts have been made to remove noise through various means, such as filtering. However, a different approach is adopted for stochastic resonance. Specifically, noise is actively used to improve system responses. For example, through the careful application of signal processing in an ecosystem, SR can be leveraged to develop a mechanism for detecting weak signals buried in noise. Applying such a mechanism in the field of telecommunications could be helpful for constructing telecommunications systems that use weak signals that cannot be detected by traditional systems. This paper presents an overview of the phenomenon of stochastic resonance ranging from initial studies to modern research trends and attempts to provide an outline of the foundational theories supporting stochastic resonance. To promote the application of stochastic resonance in the field of telecommunications, this paper then presents several concrete applications to assist readers in understanding the application of this phenomenon, such as the use of a 1 bit analog-to-digital converter to demodulate multi-level signals.
