Abstract

Balise uplink signal IQ (I: Inphase; Q: Quadrature) acquisition is an important basis for signal demodulation and uplink signal parameter estimation. Relying on traditional acquisition methods, it is difficult to achieve the requirements of automation, accuracy and real-time online analysis. In order to solve the problems existing in the traditional collection method and improve the collection efficiency of IQ signal. Based on LabVIEW as the development platform, the PXI (PCI extensions for instrumentation) system of NI is used to build a small balise test bench. Combined with the Hilbert transform principle and the characteristics of the uplink signal IQ, the uplink signal IQ acquisition system is designed. Through the actual project debugging of LabVIEW acquisition system, combined with the online analysis of the collected data, the results show that the uplink signal IQ acquisition system based on LabVIEW can effectively solve the problems existing in the traditional acquisition method and can expand the acquisition program according to the actual data processing requirements.
