Multipath Separation-Direction of Arrival (MS-DOA) with Genetic Search Algorithm for HF channels [PDF]
Advances in Space Research, 2009 Direction-of-Arrival (DOA) defines the estimation of arrival angles of an electromagnetic wave impinging on a set of sensors. For dispersive and time-varying HF channels, where the propagating wave also suffers from the multipath phenomena, estimation of DOA is a very challenging problem.
