Design and Implementation of High-Dynamic Satellite Channel Emulator

Abstract:

This paper designed a dedicated channel emulator that can be used for high-dynamic satellite channel performance testing. First of all, introduce the characteristic of satellite channel. Secondly, focusing on the analysis of Lutz model, we give the system model of the satellite channel simulation. Finally, according to the model of the system, the realization method based on FPGA platform would be given, the solution of key technology would be described and the test data would be provided.
