Abstract :
A low-complexity algorithm is introduced such that the Cramer-Rao lower bound for non-data-aided carrier phase recovery can be computed most efficiently. In the sequel, this result is used to develop a phase estimator for rotated 8/8-QAM as a powerful alternative to star 16-QAM modulated signals.
