The Real-Valued Sparse Direction of Arrival (DOA) Estimation Based on the Khatri-Rao Product [PDF]
Sensors, 2016 There is a problem that complex operation which leads to a heavy calculation burden is required when the direction of arrival (DOA) of a sparse signal is estimated by using the array covariance matrix. The solution of the multiple measurement vectors (MMV) model is difficult.
