IEEE communications letters, 2005•ieeexplore.ieee.orgWe propose a new carrier recovery algorithm for high-order quadrature amplitude
modulation (QAM). The proposed solution relies on two phase detectors, combined with a
novel track and hold algorithm for faster frequency acquisition. Compared to previous works,
a tenfold improvement or better is achieved in terms of acquisition speed, while keeping a
low residual phase noise.
