“…The resulting diagonal elements and are the covariances of the underlying feedback/echo path changes, and the power spectrum density (PSD) of the loudspeaker signal , respectively. Inserting (29) in (30) and using that , the matrix is expressed by (31) , defined in (20), follow as the diagonal elements of which are given by (32) where denotes the cross(auto) PSDs of the incoming signals and .…”

“…The algorithm by Kaczmarz, better known as NLMSnormalized least-mean-square algorithm, is widely used not only in the systems of identification of stationary [23] and non-stationary [24][25][26] system. In [27][28][29], its application to solving problems of filtration was described.…”

“…In [27][28][29], its application to solving problems of filtration was described. It should be noted that in papers [19,[24][25][26], to describe the non-stationary parameters, the first-order Markovian model was used, while papers [30,31] used the modified first-order Markovian model (this model received fairly wide use in training artificial neural networks [31]). It should be noted that the use of such a model is very convenient, because it allows receiving the analytical estimates of the dynamic properties of specific algorithms quite easily.…”
