This paper introduces a new adaptive blind equalization algorithm, 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, without using training sequences. POTEA is based on adaptive computations of the channel's power cepstrum and cepstrum of tricoherence by employing second- and fourth-order statistics, respectively. Extensive simulation results, with QAM signals, are presented to demonstrate the effectiveness of POTEA.
