In this paper, we address the problem of carrier frequency offset estimation with QPSK modulation. In particular, the method proposed here is an open-loop scheme for Non-Data-Aided (NDA) but Clock-Aided carrier recovery. Simulation results show that our method exhibits a mean-squared-error closer to the Cramer-Rao lower bound (CRLB) than other techniques proposed in the literature.
