| Summary |
This paper discusses the stochastic resonance (SR) effect in a binary communication
system for subthreshold signal reception. We focus on the problem of no communication when
received signal strength is below receiver sensitivity. Subthreshold signal reception requires a
device that exhibits SR, such as a Schmitt trigger or a comparator. Previously, we proposed
an alternative three-level device and demonstrated its high performance for subthreshold signal
reception in an SR receiver. In the present study, we show that our proposed three-level
device outperforms the three devices and discuss reasons for this superior performance. Contributions
of our present paper are twofold: first, we analytically derive bit error rate (BER)
performances of SR receivers installed with a Schmitt trigger and a comparator; second, we
compare performances of the Schmitt trigger, comparator, and three-level device. |
