A new narrowband interference suppression scheme based on time-frequency localised subspace tracking is presented. The received nonstationary signal is time-frequency-localised to extract stationary signal segments, on which reduced-order subspace tracking is applied to achieve interference suppression. Simulation reveals that this new scheme performs as well as the subspace decomposition scheme with a dramatically reduced computational complexity.
