Abstract:
|
We present a novel algorithm for the estimation of the direction
of arrival and angular distribution parameters of sources that, as a
result from the scattering effects, cannot be considered as punctual.
The algorithm is iterative and is based on the maximization
of the likelihood function associated to the received snapshots at
the antenna array (ML). It is proposed a computationally ef¿cient
method for estimating the localization and angular distribution parameters
of more than one source transmitting at the same frequency
in a noisy environment. This algorithm solves the problem
of the joint maximization in the case of two sources by formulating
two new problems of single-source ML. |
