  • Robust time delay estimation is proposed using variable step-size affine projection algorithm with M-estimators. The novel algorithm, using the structure of adaptive filter and M-estimators, is free of the assumption that the statistical characteristics of singal and noise is known. Simulation experiments under three different noise environments, Gaussian, non-Gaussian and impulse noise, are conducted to compare with the proposed TDE method using the existing Higher-Order Spectra(HOS) and Least Mean Square(LMS), and the result showes that the proposed TDE method is more robust and precision.
