摘要：
A method of measuring the carrier frequency of a phase-shift keyed signal for unknown limits of the symbols based on two readouts of the fast Fourier transform is investigated. Analytic expressions are obtained for the maximum and the mean measurement errors (with respect to the frequency and the symbol shift). The method is compared with existing measurement algorithms (based on a single readout of the fast Fourier transform).
