Abstract This paper proposes a new adaptive EP latency change estimation algorithm based on the fractional lower order moment and the nonlinear transform for the error function. The new algorithm referred to as the NLST suppresses the lower order a-stable noises without the need to estimate dynamically the a values. The computer simulation and data analysis results show that this algorithm is robust under the lower order a-stable noise conditions, and it also provides a better performance than those of the DLMS, DLMP and SDA algorithms without the need to estimate the a value of the EP signals and noises.
