....parameters. Such techniques will be called, following the current literature, recursive parameter estimations. Classical methods belonging to this class are least square estimation and its variants. A comprehensive discussion of this approach is out of the scope of this paper and can be found in [16, 9]. The basic idea is the following. At every step, the current measurements for the inputs and the outputs are used to update the = y(k 1) y(k m)u(k d 1) u(k d m) T vector; then the following equation is applied: K(k) P (k) k) k) k 1) K(k) y(k) T (k) k ....

....Varianten treten bei der Modellierung von IIR Filtern auf. 1 1 Introduction This paper provides a time domain feedback analysis of the class of Gauss Newton recursive schemes, which have been employed in several areas of identification, control, signal processing, and communications (e.g. [6, 14, 16, 17, 19, 31]) These are recursive methods that are based on gradient descent ideas and employ sample covariance matrices to control the update directions. Their descriptions involve two update relations: one for the update of the weight estimate and the other for the update of the inverse of the sample ....

INTRODUCTION This paper provides a time domain feedback analysis of the class of Gauss Newton (GN) recursive schemes, which have been employed in several areas of identification, control, signal processing, and communications (e.g. 1] [4]) These are recursive estimators that are based on gradientdescent ideas and which involve two update relations: one updates the weight estimate while the other updates the inverse of the sample covariance matrix. Several free parameters are also included in the filter description, which allows ....

....the standard LMS algorithm is applied on one data pair (input vector and desired) for an infinite number of times, the same solution as for an LS estimator on the same data pair is obtained. This property has been shown by Nitzberg [6] and from a different point of view already by Goodwin and Sin [7]. An open question, however, is what solution is obtained when the updates are performed over a set of data pairs and then repeated anumber of times, i.e. the operation of the UNDR LS algorithm. For normalized regression vectors, the Kaczmarz s row projection method (see [3] and references ....

....is best for achieving the LS solution. So far, only a constant step size has been used, 0 (l) 20) In gradient type approximation theory it is wellknown that a decreasing step size of the form 1 (l) c 1 l # l =1# 2: 21) can achieve the Wiener solution without errors (see for example [7]) Another decreasing sequence of great practical importance is given by 2 (l) c 2 2 (l ; 1) 22) since a simple multiplication can derive the following step size value. Yet, another interesting choice is 3 (l) c 2 3 (l ; 1) c 3 : 23) For all sequences it can be shown that given the ....

....to exploit the averaging properties of the disturbance. This allows it to provide better performance in terms of disturbance rejection. The mathematical foundation of this field was laid by Goodwin, Ramadge and Caines [2] and Solo [3] and the various ramifications were explored in Goodwin and Sin [4]. Also, for identification, Lai and Wei [5, 6] and Chen and Guo [7] have determined sharp estimates of the rate of convergence of several parameter estimation algorithms.

....here we choose the RLS algorithm for the on line bandwidth prediction of video traffic. Since each bandwidth adaptation requires computation of the predictions fx L (n D) xL (n D 1) x L (n D M )g, the so called indirect prediction approach is used to avoid redundant computation [9]. That is, instead of directly constructing (M 1) RLS prediction filters, we construct a single RLS filter to perform parameter estimation of a given autoregressive (AR) model of the time series. The (M 1) predictions are then obtained by converting the model into the required predictor ....

....can be detected and used to predict the future over time scales relevant to congestion control. Time series analysis and prediction theory has a long history with techniques spanning a number of domains from estimation theory to regression theory to neural network based techniques to mention a few [3, 17, 22, 40]. In many senses, it is an art form with different methods giving variable performance depending on the context and modeling assumptions. Our goal is not to perform optimal time series prediction but rather to choose a simple, easy to implement scheme and use it as a reference for studying ....

....condition on the inverse to exist. Definition 1: The input is said to be persistently exciting (PE) of order k at time n if T k (a n ) has full (column) rank. That is, to determine the channel, the input must be PE of order q. This definition is quite common in adaptive control, see e.g. [3], although a similar asymptotic condition is more common in system identification. However, the main purpose of this paper is to identify the input, and generally it is easier to estimate the input to a linear, time invariant system than to identify the coefficients in the system.
