Multipath and precorrelation filtering effect on GPS noncoherent early-minus-late power discriminators.

The performance of GPS delay lock loop (DLL) can be greatly compromised by multipath. This paper considers the effects of multipath on the GPS receiver. It evaluates the DLL performance in terms of the tracking error of the noncoherent early-minus-late power discriminator. We discuss the effect of precorrelation filter bandwidth on the autocorrelation function of the GPS spreading code and subsequently, on the DLL signal tracking. The tracking error, which is influenced by the precorrelation filter bandwidth, is analyzed.
