Abstract :
This paper proposes an improved implementation of the subspace projection method aiming to minimize the near-far effect that occurs in Global Navigation Satellite System receivers. Our technique does not demand phase estimation of the strong signals, thus being suitable for non-coherent receivers. Simulation results demonstrate the effectiveness and the limitations of the proposed mitigation technique.
