Abstract
This work derives general formulas for the widely known constant modulus algorithm (CMA) and multimodulus algorithm (MMA) error surface curvatures at all of the stationary points with arbitrary symmetric two-dimensional signal constellations, regardless of the in-phase and quadrature dependency of the source symbols. Once these curvatures are computed, the effect of the source distributions on the capabilities of equalizer convergence and phase tracking may be accurately predicted and evaluated.
