Abstract

According to the characteristic of impulsive noise environment, a new class of time delay estimation algorithms which combine the nonlinear preprocess and variable step-size adaptive time delay estimation is presented in this paper. The performance of these new algorithms is compared with traditional time delay estimation method under both Gaussian and impulse noise environment. The results show that the new methods can achieve better effect on robustness, convergence rate and delay precision.
