Parameters influence analysis of dynamic light scattering signal simulation method of wavelet transform

At different simulation parameters such as decomposition scale, data length and sample frequency, by analyzing consistency degree of theory power spectrum and power spectrum of simulation signal, this paper studies the influence of simulation parameters on simulation effect for dynamic light scattering ( DLS) signal simulation method of wavelet transform. Research show that, at same other two simulation parameters, the small particles need smaller decomposition scale, the big particles is contrary, too big data length and sample frequency, too small sample frequency can lead to poor simulation effect. In practice simulation, the three parameters are mutually constraints.
