Angle-perturbed sources AOA estimation for wireless mobile communications.
Suk Chan Kim, Iickho Song · 2005
If the direction of arrival (DOA) of a source is perturbed due to some reasons in a statistical way as in the environment of wireless mobile communications, a new model appropriate 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. KEY WORDS angle of arrival, angle-perturbed source, wireless communication 1
