A nonminimum-phase channel can always be decomposed into a minimum-phase part and an all-pass part. In our approach, called all-pass CMA, the dimensionality of the CMA algorithm has been reduced to improve blind equalization of a nonminimum-phase channel's all-pass part. The dimensionality reduction has been performed by parameterizing the CMA cost function in terms of the nonminimum-phase zero location of the all-pass part to be compensated. Currently, all-pass CMA can only compensate a single nonminimum-phase zero. However, compared to CMA, it typically provides a faster and more accurate compensation of this zero.
