Abstract :
In order to satisfy sending multi-channel navigation signals in one frequency for modern GNSS(Global Navigation Satellite System), the principle of Interplex multiplexing were introduced. And the three-way multiplexing structure and the four-way multiplexing method were also optimized. The Galileo E1 signal, as the example of Interplex reuse, was analyzed in detail. The power configuration of the multiplexing efficiency and the minimum of the multiplexing efficiency were obtained.
