Summary:
Stochastic Resonance (SR) is considered as a noise enhanced phenomenon, that a response of a non- linear system is improved by noise. In previous studies, an application of SR for wireless communication has been discussed and an SR receiver, the receiver that demodulate a received signal by SR, was proposed. However, these studies have used a basic modulation signal and have not focused on a signal that transmit information by multi-level amplitude. In this paper, we consider an SR receiver for 4-PAM signals. By applying SR, it can demodulate 4-pulse amplitude modulation (4-PAM) signals by a 1-bit resolution device. We show the system model of the receiver, evaluate its performance by simulation, and show its availability.
