A new output error based parameter estimation algorithm for a class of nonlinear systems and its applciations to noise reduction in speech

摘要

In real life,noise that corrupts speech signals in many practical situations is one of the major factors that degrades speech intelligibility.An algorithm based on the output error method is proposed to reduce noise in nonlinear systems that can be represented by input/output polynomial models.To assess the performance some examples are provided using real time speech signals.
