    Abstract: A method for calculating a reconstructed phase that includes: Calculating a current phase signal and current amplitude signal that represent a phase and amplitude of a current input symbol, respectively. Generating, in response to the current phase signal and an estimate of a phase of a last input symbol that preceded the current input symbol, multiple partial references, some of which are responsive to (i) phase signals representative of phases of a plurality of input symbols that preceded the current input symbol, and (ii) estimates of the phase of the plurality of input symbols. Calculating unwrapped partial references. Estimating a constant carrier frequency offset (CFO) phase rotation in response to the unwrapped partial references. Calculating a reconstructed phase of the current input symbol in response to, at least, the estimate of the constant CFO phase rotation and to the unwrapped partial references.
