An Improved Navigation Pseudolite Signal Structure Based on the Kasami Sequences and the Pulsing Scheme
文献摘要：
Pseudolites(PLs)are ground-based satellites,providing users with navigation solutions.However,implementation of the PL system leads to the near-far problem.In this paper,we proposed an im-proved navigation PL signal structure of combing Kasami sequences and the pulsing scheme to mitigate the near-far effect.The pulse modulation method is adopted to ensure that the PLs transmit signals at different timeslots and reduce the PL signals'mutual interference.Additionally,we employ the small set of Kasami sequences with good cross-correlation properties to improve the anti-interfer-ence ability.A simulation test based on software is car-ried out to evaluate the performance of the proposed sig-nal.The simulation proves that the improved PL signal has an impulsive power spectral density,makes it a feas-ible solution to mitigate the near-far effect,and performs better in the capture.
