Abstract

In this paper, we derive the CRLB (Cramer-Rao Lower Bound) of effective carrier-to-noise power ratio (<TEX>$C/N_0$</TEX>) estimation for a GPS (Global Positioning System) L1 C/A (Coarse/Acquisition) signal under band-limited white noise jamming environments. The quality of a received GPS signal is commonly described in terms of its <TEX>$C/N_0$</TEX>, implying that the noise is white and thus can be described by scalar noise density. However, if some intentional interference is received to a victim GPS receiver, then the <TEX>$C/N_0$</TEX> is no longer the efficacious performance indicator. The correct and straightforward measurement to analyze the receiving situation is the effective <TEX>$C/N_0$</TEX>. In this paper, we consider a band-limited white noise jamming whose bandwidth is 2MHz and is the same as one of the first null-to-null bandwidth of the GPS L1 C/A signal.
