Abstract

We propose a new blind equalization technique based on second and fourth order cumulants. The algorithm proposed will equalize the second and fourth order cumulants of the input and output sequences. It is entirely driven by statistics, only requiring knowledge of the variance (power) of the input signal. Because of insensitivity of the higher-order cumulants to Gaussian processes, the algorithm performs well with additive Gaussian noise. Simulation examples are presented in which the proposed technique is compared with other existing equalization algorithms.
