Abstract

The application discloses a satellite load simulator for asymmetric PCMA, the satellite simulator includes: at least two signal processing circuits, at least two signal branching circuits, multi-user hinge relationship simulation module and interface processing and comprehensive control module; the interface processing and integrated control module is used to adjust the signal processing parameters of each signal processing circuit; each signal processing circuit is used to combine and convert multiple signal beams to obtain digital signals, and process the digital signals according to the signal processing parameters The user hinge relationship simulation module is used to determine the link information of the user, and forwards the processed signal to a signal branching circuit according to the link information; each signal branching circuit is used to receive the processed signal, The processed signal is subjected to frequency conversion conversion processing, and the frequency conversion analog signal is subjected to split processing. This application fills up the technical problem of the satellite simulator blank of the distributed HTS communication system.

Description

technical field [0001] The present application relates to the technical field of satellite simulation, in particular to a satellite load simulator for asymmetric PCMA. Background technique [0002] In the distributed high-throughput satellite (High Throughput Satellite, HTS) communication system, user terminals communicate through outer space satellite transponders. Since the communication process is completely dependent on satellite space resources, but given that the existing space resources on the satellite are insufficient , the paired carrier multiple access (PCMA), which can double the system capacity, is applied to the HTS communication system. Due to the difficulty and high cost of conducting experiments on real satellites, in order to improve the efficiency and quality of distributed HTS communication products developed, a satellite simulator that can truly and stably simulate multi-user hinges on satellites is needed. [0003] see figure 1 , the current process o...
