摘要：
Judicious selection of the step size parameter is often necessary for satisfactory performance from gradient-based adaptive algorithms for nonstationary time delay estimation. This paper provides two variable step size techniques for these algorithms which allow for fast initial adaptation. Simulations are provided which verify the useful behaviour of these methods.
