Abstract (in Japanese) (See Japanese page) 
(in English) In this study, a modified particle filter considering non-Gaussian properties of noises is proposed in a form applicable to real situation in sound environment system where the observation data are contaminated by the external noise (i.e., background noise) of arbitrary probability distribution and measured in a quantized level form. More specifically, a nonlinear observation model with the quantized observation in decibel scale is first paid considered by introducing the additive property of power state variables in sound environment system. Next, a particle filter of an extension type is derived in a form suitable for the quantized observation data and the signal processing considering higher order correlation information between the specific signal and observation. Furthermore, the effectiveness of the proposed theory is confirmed by applying it to the observed data measured in real sound environment.
