. Blind synchronization of received DS-SS/BPSK signal can achieve with sliding correlation based on fractionally sampling by taking full advantages of edge auto-correlation property of DS-SS pseudo-random noise (PN) code and picking-up one PN code time period DS-SS/BPSK signal as known PN code on given PN code period Theoretic analysis and simulation show that the synchronization precision is dependent on the signal to noise ratio (SNR), length period of PN code, fractionally sampling coefficient and data segments. Therefore, blind synchronization of received DS-SS/BPSK signal at lower SNR (-17dB) can achieve efficiently at cost of a certain computation complexity.
