摘要：
In this paper, we have proposed an adaptive source localization method. The block LMS method has been used in channel estimation and noise reduction. In this paper, the block LMS method has been used for the source localization and the analysis of the mean square error performance has been carried out in the source localization formulation. The performance of the proposed method has been found to be superior to the existing least squares-based methods under various noise situations. Furthermore, under non-stationary environment, the proposed method can estimate the position without estimating the noise variance. (C) 2010 Elsevier Inc. All rights reserved.
