Abstract：Symbol rate estimation of PSK signals could be effectively implemented by employing the cyclic-autocorrelation function or cyclic-autocorrelation based cyclic statistics. Stationary noise, which does not possess cyclostationarity, has an influence on cyclic-autocorrelation based PSK symbol rate estimation in practice, and this is not consistent with the theoretical analysis. The origin of such influence is studied in this paper, and the analytic expressions of means and variances of those undesired items (which are produced by stationary noise), as well as the simplified forms for Gaussian white noise are derived. Simulation experiments have testified the analytic results.
