Evaluation of Multipath Effects on Interference Cancellation in GNSS using Space-Time based Array Processing
نویسنده
چکیده
Space-time adaptive processing is a powerful tool for interference rejection. However, its performance may significantly degrade in the presence of multipath. Due to the coherence between the multipath of the interference, adaptive methods are not able to satisfactorily remove the interference. In this paper, we present a simulation study to quantify the degradation of a common adaptive method in different multipath scenarios. Both spread-spectrum and narrowband interference sources are considered. Particularly, performance analyses versus the angular and delay separations between the line of sight and multipath components of the interference are investigated. Insightful conclusions are drawn.
