Abstract

This paper attempts to predict and evaluate both the equalization performance and the carrier phase recovery performance of the multimodulus algorithm (MMA) and the constant modulus algorithm (CMA) followed by a blind carrier phase recovery algorithm (CPRA) with arbitrary two-dimensional symmetric signal constellations based on their error surface curvatures in the neighborhoods of the stationary points.
