Asynchronous DS-SS CDMA Random Spreading Code Correlation Statistics in the Presence of Timing Error
David W. Matolak · IEEE Transactions on Vehicular Technology · 2005
We quantify the effect of timing tracking errors upon 2nd order correlation statistics of random binary spreading codes and, in so doing, fill a gap in the literature. Using a Gaussian model for timing tracking error, new expressions for autocorrelation statistics are derived. For crosscorrelations, we show that a zero mean Gaussian timing error has no effect upon 2nd order crosscorrelation statistics.
