Abstract :
An important problem in wireless communications, and more especially in array processing, is the estimation of directions-of-arrival (DOA) of sources on an array of sensors. This is increasingly complicated if signals received by sensors are scattered. The paper presents two new methods for estimating the DOA and angular spread of scattered sources. The performances of our estimators are investigated by simulations.
