摘要

The processes observed in a sound environment inevitably contain additional external noise of arbitrary distribu- tion. Furthermore, the actual sound environment system exhibits various types of linear and non-linear characteristics, and it of- ten contains an unknown structure. In this paper, a method for estimating the input signal for a sound environment system with unknown structure and additive noise of arbitrary probability distribution is proposed by introducing a system model of the conditional probability type.
