Research on Localization Algorithm with 5G Opportunistic Signals in Co-channel Interference Environments
In response to the challenge of ensuring positioning accuracy in environments where the Global Navigation Satellite System(GNSS)is denied,a positioning scheme based on opportunistic New Radio(NR)signals is devised and an Interference Cancellation Subspace Pursuit(ICSP)algorithm is proposed in this paper.This algorithm aims to resolve the issue of inadequate precision in the extraction of positioning observations due to co-channel interference within Ultra-Dense Networks(UDNs)and Heterogeneous Networks(HetNets).The effectiveness of the ICSP algorithm in optimizing the performance of 5G opportunistic signal receivers and enhancing positioning accuracy in complex network environments has been validated through simulation experiments and semi-physical simulations utilizing the Universal Software Radio Peripheral(USRP).
