Abstract

If the direction of arrival (DOA) of a source is perturbed due to some reasons in a statistical way as in the environ ment of wireless mobile communications, a new model ap propriate for such environment should be used instead of the point source model. In this paper, an angle-perturbed source model is proposed and an estimation method based on the eigen-decomposition technique is investigated under the model. The asymptotic distribution of the estimation errors is obtained to see the statistical properties.
