Abstract

Blind synchronization of minimum-shift-keying signals in the context of time-selective fading communication channels is considered. Strictly feedforward algorithms based on second- and fourth-order cyclic statistics are proposed for frequency and timing offset estimation. The new estimators are shown to outperform existing methods. Extensions of the algorithm to GMSK are also studied. Finally, fourth-order cyclic statistics are shown to provide an accurate estimate of the Doppler spread
