Analysis of Quasi-Zenith Satellite System Signal Acquisition and Multiplexing Characteristics in China Area

open access: yesSensors, 2020
On the basis of realizing regional navigation, the Quasi-Zenith Satellite System (QZSS) has advanced navigation function, which leads to the broadcasting of more signals in a single frequency of QZSS signals. Current signal transmission technology cannot
