Comprehensive Interference Analysis for ZC-NOMA

In order to realize the integration of communication and navigation on LEO, a new waveform named ZC-NOMA was proposed in the previous study, which was proved to achieve reliable navigation function without significantly affecting the communication performance. In this paper, factors affecting the performance of ZC-NOMA signals, including inter-satellite asynchronous access interference and interference between communication and navigation components, are comprehensively discussed. In addition, the whole process of communication signal processing is also clearly demonstrated in the form of simulation. The analysis results show that through reasonable parameter configuration, the interference level can be effectively controlled and the integration of communication and navigation functions can be realized.
