| Sumario: | Global Navigation Satellite Systems (GNSSs) face a difficult challenge when combating multipath reflections, since, due to their high correlation with the signal of interest, they pose a significant threat for GNSS receivers. The use of array processing techniques greatly helps receivers to combat these effects, typically exploiting available information for an effective mitigation. However, relying on external and possibly out-dated references might cause the receiver to perform poorly, and thus an approach that does not require any previously obtained parameters can significantly enhance the behaviour of the receiver. This paper presents a blind alternative to the reference-dependent existing techniques for multipath mitigation in GNSS receivers. Combining two well-known algorithms, SAGE and LMS, this approach allows to obtain large attenuation capacities while ensuring resilience and robustness against rapid changes in the operating environment. |
