Frame synchronization method for prolate spheroidal wave function modulated signal

A frame synchronization designing method is proposed for prolate spheroidal function(PSWF) modulated signal.By analyzing the PSWF pulse inherent characters，the band-pass frame synchronization sequence is designed by PS code modulated PSWF signal at transmitter，which is with unimodality in its envelope.An envelope detector constructs the received synchronization sequence into a new frame synchronization sequence，which is with unimodality in its auto-correlation at receiver，and then the synchronization signal is captured.
