Multi-component harmonic retrieval finds applications in many fields, including radar, sonar and wireless communications. In previous years, several high-resolution subspace-based techniques have been proposed to overcome the spectral leakage problems inherent in the conventional periodogram. However, these methods require high SNR and/or white noise, and are highly computationally intensive in scenarios with a large number of spectral components. We propose a frequency domain subspace… CONTINUE READING
