On the Statistical Properties of GNSS Modulation

Francois Cote, Ioannis N. Psaromiligkos, Warren J. Gross

Abstract:	Binary offset carrier (BOC) modulation has become the technique of choice for interoperable signal augmentation in Global Navigation Satellite Systems (GNSS). The family of BOC signals can be extended to allow a more general description of current GNSS signal theory. By using convolution in order to mathematically define all BOC subcarrier waveforms, a generalized formulation for the autocorrelation function (AF) and power spectral density (PSD) of GNSS signals is developed. This unified theory permits rapid simulations to obtain key performance indicators such as signal disparity and tracking potential. It is shown that the analytical formulation can be used to describe multipath effects within the constraints of a statistical channel model or simply with specular error envelopes.
