Robust DOA Estimation in Co-prime Arrays with Impulsive Noise using EBNC-PFLOM Method
Résumé
Recently, direction-of-arrival (DOA) estimation in impul-
sive noise scenarios has been extensively investigated in the
field of co-prime array signal processing. This paper pro-
poses a combined enhanced bounded nonlinear covariance
and phased fractional low-order moment (EBNC-PFLOM)
method, which incorporates the advantages of both EBNC
and PFLOM and mitigates the impulsive noise by construct-
ing the equivalent data covariance matrix of the received
signals. Furthermore, when dealing with a limited number
of input signals, the proposed method is capable of directly
estimating the signals’ DOA without spatial smoothing. Sim-
ulation results show that the proposed method outperforms
the recently reported methods.
