Abstract
In this paper we present a new method for localization of wideband sources in the presence of colored noise. The optimization criterion used is an extension of conventional least-squares method known as generalized least squares (GLS). The crux of the criterion is based on covariance matching and involves its transformation that yields a more efficient and consistent estimate of the direction of arrivals (DOAs) as compared to the LS and GLS methods that are only developed in the literature for narrowband sources
