S N R
is plotted as a function of multiplicative noise intensity D with A = 0.08 and Ω = 0.001, the other parameter values are the same as those in Figure 2. The sold line on the left column represents the theoretical results (Eq.(31)), while the dot line on the right column is for the numerical results. From top to bottom, the results for different delay time with α = 0.01, λ = 0.5 in (a) and (b), for different additive noise intensity with τ1 = 0.1, λ = 0.5 in (c) and (d), for different correlated noise intensity with τ1 = 0.1, α = 0.015 in (e) and (f), are provided.
