Partial Correlation Properties of Pseudonoise (PN) Codes in Noncoherent Synchronization/Detection Schemes
D. E. Cartier · IRE Transactions on Communications Systems · 1976
This concise paper considers the effect on the autocorrelation function of a pseudonoise (PN) code when the acquisition scheme only integrates coherently over part of the code and then noncoherently combines these results. The peak-to-null ratio of the effective PN autocorrelation function is shown to degrade ton^{-1/2}, wherenis the number of PN symbols over which coherent integration takes place.
