The Ground-based Radio Navigation System (GRNS) is an alternative/backup navigation system based on time synchronized pseudolites. It has been studied for some years due to the potential vulnerability issue of satellite navigation systems (e.g., GPS or Galileo). In the framework of our study, a periodic pulsed sequence was used instead of the randomized(More)
In this paper, we show that the cross-correlation of two properly chosen column sequences from the array structure of two different Sidelnikov sequences of periods q<sup>e</sup>-1 and q<sup>f</sup> - 1, where e &#x2260; f, is bounded by (e+f-1)&#x221A;q+1. From this result, we construct new sequence families by combining sequence families from the array(More)
