Weak GPS Signal Acquisition Using Antenna Diversity
… is required. A common method is to extend the coherent integration time. However, in weak signal situations, using only long coherent integration is limited by navigation data bit transitions and receiver oscillator instability. Using non-coherent and differentially coherent integration …

Improving High Sensitivity GNSS Receiver Performance in Multipath Environments for Vehicular Applications
… receiver scheme with more correlators and/or longer coherent integration time, this thesis aims to obtain better positioning performance in the urban canyon areas. It was reported that signal correlation peaks (e.g., LOS correlation peaks, multipath correlation peaks) may be separated in the …

Observation of Low Earth Orbit Debris using GNSS Radar
… signal is large and non-linear during the integration period. Due to this non-linearity, the receiver experiences different relative carrier phases throughout the observation period, so the cross-correlation interference is not persistent. We have shown that on the order of minutes, signals …
