A HYBRID BEAMFORMING APPROACH TO ANTI JAMMING FOR MULTI CHANNEL GNSS RECEIVERS

We consider the problem of anti-jamming in GNSS navigation. In this work, we introduce the novel concept of a hybrid beamforming approach to antijamming for multi-channel GNSS receivers.

Nenkova et al. (2006) show that using term fre- quency is a powerful approach to modeling human summarization. Nevertheless, for SumBasic to per- form well, stop-words must be removed from the composition scoring function. Because these[r]

Multi-cell wireless systems usually suffer both intracell and inter-cell interference, which can be mitigated via coordinated multipoint (CoMP) techniques. Previous works on multi-cell analysis for the microwave band generally consider fully digital beamforming that requires a complete radio-frequen[r]

In this chapter we have investigated how the required transmitter power of each sensor node is affected by the number of cooperating transmission nodes in a traditional random beamformer array. Due to the randomness of the sensor node positions, there is no simple algorithm for[r]
