PN Sequence Period Estimation Method for Underwater Direct-Sequence Spread Spectrum Signals Under Low SNR

In non-cooperative DSSS signal reception, the accurate estimation of the pseudo-noise (PN) sequence period is essential for successful despreading and information recovery. In this paper, we propose an average second-order-moment autocorrelation method based on the accumulated code difference functi...
