Abstract
We propose an online time-frequency (TF) projection filter with reasonable computational complexity for signals of arbitrary length. The filter uses local projections and TF subspace tracking based on an efficient iterative eigendecomposition. The high TF selectivity of the online TF projection filter is shown to be advantageous for interference excision in spread-spectrum communications.
