A novel decorrelation algorithm that can eliminate the computation of MUSIC without having aperture loss is presented. Through vector reconstruction by eigenvector of maximum eigenvalue, the algorithm can deal with coherent signal sources. Furthermore, Using MUSIC technique based on whole space and Modified Capon algorithm,high estimation capability can be acquired without knowing the number of signals. Simulation results verify that the proposed algorithm is effective.
