Outline of Final Research Achievements

Stochastic resonance (SR) is an interesting phenomenon in that noise enhances system response. Despite attractive phenomenon of SR that noise enhances system response, enhancement of the weak signal below device sensitivity, and few researchers have addressed the SR effect in communication systems. This study challenges the SR effect in communication systems. The research focuses on the problem in which communication cannot be established when the received signal strength is below receiver sensitivity. Overcoming receiver sensitivity introduces new and attractive challenges in wireless communication systems. If receiver sensitivity can be lowered, we can simultaneously reduce transmission power and interference to other users. Low-power wireless systems can provide solutions for both energy-efficient green wireless communications and wireless spectrum shortage.
