An Adaptive Receiver Approach to the Time Synchronization Problem
Paul A. Wintz, J. C. Hancock · IRE Transactions on Communications Systems · 1965
In this paper, a frequency shift keying (FSK) system that adapts to unknown signal arrival times is defined and analyzed. The adaptive receiver extracts information concerning the signal arrival times directly from the information bearing signals and uses these measurements in a structure known to be optimum for the case of perfect measurements. The system error rate is derived and plotted as a function of the received SNR, the size of the signal alphabet, and the quality of the delay measurements.
