Abstract
Multi-user detection (MUD) techniques are applied to the GPS interference suppression/rejection problem, such that recovery of GPS satellite signals out of an environment contaminated with one or more correlated interference sources is afforded. In modeling the narrowband digital interference as a set of multiple users it is shown that recovery is possible via any of several MUD algorithms, including the conventional detector, the decorrelating detector, the optimum linear detector, and the minimum mean square error (MMSE) detector. The relationship between the underlying structure of the GPS symbol (C/A code) and the performance of these detectors is studied such that bit error rate (BER) and signal-to-interference ratio (SIR) are developed analytically.
