Abstract

This paper introduces a blind adaptive carrier phase offset recovery scheme based on the constant modulus (CM) algorithm and analyzes its behavior. The proposed CM-derotator (CMD) minimizes the dispersion of the real projection of the derotated signal to remove the phase offset of the signal. By analyzing the cost function, the performance of the CMD is investigated in various situations including its tracking ability, its behavior in the presence-of intersymbol interference, and when there are statistical dependencies between the in-phase and quadrature components
