Yang Taoliu, Wei Zhang, Zhao Xiufen · 2012
In this paper an new ESPRIT algorithm based on the solution of rotation invariance relationship (SRI-ESPRIT) is proposed, providing an new solution to the general class of ESPRIT technique. The proposed new algorithm provides low computational complexity and good accuracy as compared with other ESPRIT variations. Demonstration has evaluated the validity of the method on simulated data by plotting of spatial spectra.
