Iterative Shrinkage Operator for Direction of Arrival Estimation
Yousaf M. Rind · International Journal of Information Engineering and Electronic Business · 2016
In this correspondence we present the application of iterative shrinkage (IS) operator to the DOA estimation task.In particular we focus our attention to Stage wise Orthogonal Matching Pursuit (StOMP) algorithm.We compare StOMP against MUSIC, which is state of the art in DOA estimation.StOMP belongs to compressive sensing regime where as MUSIC is parametric technique based upon sub-space processing.To best of our knowledge IS operators have not been analyzed for DOA estimation.The comparison is performed using extensive numerical simulations.
