Adaptive structured eigenvector methods

Research output: Contribution to journalConference article


An adaptive eigenstructure method for angle-of-arrival estimation is presented. This method consists of applying subspace iteration to a special structured basis of the signal or noise subspace. At each iteration, the method eliminates the spurious zeros associated with the degeneracy of the noise subspace and provides estimates of the zeros containing the desired angle-of-arrival information. Thus, it is well-suited for tracking nonstationary sources. The method is the adaptive version of the reduced MUSIC block processing method.
