Abstract :
In this paper, a new approach of 2-D MUSIC algorithm was proposed. Using the eigenvector and the eigenvalue of the covariance matrix simultaneously, this method dispenses with 2-D searching. The computation load of this 2-D method is alleviated effectively. The pairings of the estimated parameters are automatically determined and the estimation precision is high. Simulation results are presented to demonstrate the performance of the proposed method
