误码率与随机共振

Symbol Error Rate and Stochastic Resonance

用Matlab语言的simulink软件,构成一面向结构,而且可以定量分析非线性双稳系统随机共 振现象的计算机仿真实验系统,并对输入字符串信息的符号误码率随噪声振幅变化的实验数据进行了拟 合,验证了非线性系统特有的随机共振现象的存在.

By Simulink software in Matlab language, a structure-oriented computer simulator is designed and a stochastic resonant phenomenon on the nonlinear system with bistable potentials is quantitative analyzed in this paper. The experimental date on symbol error rate of character string information with the noise amplitude is fitted. A stochastic resonant phenomenon on a nonlinear system is validated
