Abstract :
The major problem with the MUSIC algorithm is numerous computations for eigendecomposition. The author gives a novel MUSIC algorithm which constructs the projection matrix using the residual vectors produced during solving special simultaneous equations by the complex conjugate gradient method. To test the performance of the proposed algorithm, some simulation results are given
