RESOLUTION ENHANCED ESPRIT

We present a variant of ESPRIT, known as the resolution enhanced (RE)- ESPRIT, that lowers resolution thresholds by incorporating left weight ing of the signal eigenvectors to provide sector focusing. We discuss the advantages of this new left weighted ESPRIT. A compact expression for the asymptotic covariance matrix of the estimates is presented. An alytical and simulation results are included to show the resolution im provement of ESPRIT.
