The adaptive sr , studied in this thesis , means that the system automatically selecting parameter with a recursive algorithm , not adaptively adding noise . a parallel connection sr system is introduced and its application in digital frequency shift modulation signal transmission is discussed
我们初步提出了参数自适应随机共振的思想以及收敛算法，同时，我们还研究了数字信号载波调制传输中的并联随机共振系统。
