Results from an Analytical Model for GNSS Receiver Implementation Losses

C.J. Hegarty, A.P. Cerruti

Abstract:	Global Navigation Satellite System (GNSS) receivers suffer signal-to-noise ratio (SNR) losses due to bandlimiting, quantization, and sampling. This paper presents results from an analytical model for GNSS receiver losses for a wide variety of practical scenarios. The model, derived in a previous paper and summarized herein, addresses digitization of the received signal by a uniform quantizer with an arbitrary (even or odd) integer number of output levels. The model provides SNR loss values for GNSS signals in the presence of both additive white Gaussian noise and interference, provided that the interference can be accurately modeled as a non-white, Gaussian wide sense stationary process.
