Stochastically Resonant Spectrum Sensing Signal-to-Noise Ratio Improvements for Dynamic Spectrum Access Cognitive Radios

摘要

This paper investigates Stochastically Resonant Spectrum Sensing (SRSS) for Dynamic Spectrum Access (DSA) in TV White Space (TVWS) radio networks. We employ a typical Overdamped Bi-stable Oscillator and demonstrate the effect using Additive Noise as a base model and the impact of logarithmically scaled Stochastically Resonant Noise as well as various different distributions for the injected SR Noise.
