  • For the issue of the synchronization in nonsinusoidal orthogonal modulation signal in time domain based on Prolate Spheroidal Wave Functions (PSWF), a synchronization algorithm based on auxiliary sequence is proposed by analyzing the pulses sequence characters. The auxiliary sequence with single peak value is designed by using time-limited baseband PSWF pulses with first order modulated by Barker code. Synchronization is firstly achieved to within a reasonable phase sector in short time by using of serial-search slider coherent acquisition, then fine acquisition is achieved and the accuracy is verified by using MAX/TC algorithm. The performance of the synchronization algorithm is derived under the additive white Gaussian noise by theory analysis. The simulation result shows that the proposed synchronization algorithm is feasible and with high acquisition probability under low signal noise ratio.
