Abstract
Fast algorithms for computing signal subspace frequency or bearing estimates without eigendecomposition were described. These algorithms are based on the LR and the power methods for computing the eigendecomposition of matrices. Signal and noise subspaces were then utilized to develop high resolution methods such as MUSIC and ESPRIT for sinusoidal frequency and direction of arrival (DOA) problems. A simple squaring procedure was suggested which provides significant computational saving in comparison with methods based on exact eigendecomposition. Simulations showing the performance of these methods will also be presented.
