A Conjugate-Cyclic-Autocorrelation Projection-Based Algorithm for Signal Parameter Estimation
EURASIP Journal on Wireless Communications and Networkingvolume 2006, Article number: 086026 (2006)
A new algorithm to estimate amplitude, delay, phase, and frequency offset of a received signal is presented. The frequency-offset estimation is performed by maximizing, with respect to the conjugate cycle frequency, the projection of the measured conjugate-cyclic-autocorrelation function of the received signal over the true conjugate second-order cyclic autocorrelation. It is shown that this estimator is mean-square consistent, for moderate values of the data-record length, outperforms a previously proposed frequency-offset estimator, and leads to mean-square consistent estimators of the remaining parameters.
