The Cramér-Rao Bound (CRB) for direction of arrival (DOA) estimation has been extensively
studied over the past four decades, with a plethora of CRB expressions reported for various …

In bistatic multiple input multiple output (MIMO) radar, more number of detectable incident
signals and a higher angle estimation performance can be obtained by using conjugate …

In this paper, the problem of off-grid direction of arrival (DOA) estimation for the more
general case of coexisting circular and non-circular signals is investigated from the …

Direction of arrival (DOA) estimation via sparse signal recovery (SSR) has recently attracted
a considerable research interest due to its various advantages over the conventional DOA …

Estimating the directions of arrival (DOA) of coexisting circular and strictly second-order (SO)
non-circular (NC) signals has recently emerged as an active field of research. In previous …

In direction finding, the use of noncircularity of signals arriving at a sensor array can allow us
to improve estimation performance. It will be more realistic, rather than the assumption of all …

In practice, there are many circular and non-circular signals due to multipath propagation
and various modulations. Conventional direction-of-arrival (DOA) estimation in a mixture of …

The Cramer-Rao bound (CRB) offers insights into the inherent performance benchmark of
any unbiased estimator developed for a specific parametric model, which is an important …

In this paper, the problem of direction-of-arrival (DOA) estimation for the mixture of circular
and non-circular signals is considered and a new sparse signal recovery (SSR) based …

Abstract Direction-of-arrival (DOA) in coprime linear array involves the problem that existing
algorithms have less taken signal features into consideration. Considering that there is …
