....s and s . We model the different physical media, the signal passes through, as two linear systems whose frequency response is denoted by H and H . In addition the signals are contaminated with noise that may account for non linear effects such as room reverberations (see for instance [3] for more detailed noise models) Thus, the received signals can be written in the time and frequency domain as, S # l s # s # l (1) S # r s # s # r . 2) Since the source signal is typically non stationary we break each training and test signal into segments and perform ....

....Nevertheless, the numerical study in [5] clearly demonstrated the adverse effects of reverberation. The purpose of the present paper is analyze of the problem of acoustic source localization in a reverberant environment. The statistical analysis is based on a model proposed in a companion paper [7]. Using the model of [7] several interesting results are derived. Among others, we will derive the CRB for estimation of 0 . II.

....fading is a well researched problem (see for example [8] The introduced reverberation model is in fact quite similar to Ricean fading . However, because of the broadband nature of the signal, the signal is divided into subbands and model is suitably adapted for eachband. In a companion paper [4], the new model is applied to derive relevant Cram erRao lower bounds to understand localization accuracy limits. In addition, the accuracy of common time delay estimators are analyzed, and the probability of an anomalous estimate is derived. II. Elements of the New Model In this section we will ....
