随机共振（SR）通过增加噪声来增强系统响应。通过将SR应用于接收机，可以接收常规线性接收机不能接收的亚阈值信号。在此之前，我们提出了一种使用比较器的SR接收机的分析方法，并评估了其误比特率性能。比较器被认为是一个简单的非动态系统，表现出SR。然而，动态系统可以有更好的性能，因为它具有记忆效应。在这个意义上，我们提出了一种分析方法的SR接收机使用一个施密特触发器被称为一个简单的动态系统，并评估其误比特率性能。还示出了比较器和施密特触发器的性能比较。
Stochastic resonance (SR) enhances system responses by increasing noise. By applying SR to a receiver, a subthreshold signal not receivable by a conventional linear receiver could be received. Previously, we proposed an analysis method of the SR receiver using a comparator, and evaluated its bit error rate performance. The comparator is known as a simple non-dynamical system exhibiting SR. However, a dynamical system can have better performance since it has a memory effect. In this sense, we propose an analysis method of the SR receiver using a Schmitt trigger known as a simple dynamical system, and evaluate its bit error rate performance. A performance comparison of the comparator and the Schmitt trigger is also shown.
