POTEA: the Power Cepstrum and Tricoherence Equalization Algorithm

This paper introduces a new adaptive blind equalization method, the Power Cepstrum and Tricoherence Equalization Algorithm (POTEA), based on second- and fourth-order statistics of the received sequence. The algorithm performs simultaneous identification and equalization of a nonminimum phase channel from its output only. Simulation results, with QAM signals, are presented to demonstrate the effectiveness of POTEA.
