Embodiment Construction

[0047] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0048] see figure 1 , the embodiment of the present application provides a gateway station demodulation performance analysis system 10, the system 10 may include: a tester 11 and a tested gateway station 12, wherein the tester 11 and the tested gateway station 12 can be Wired connection is used to avoid the impact of external interference signals on the test.

[0049] Specifically, as figure 1 As shown, the signal output by the tester 11 is generally an intermediate frequency signal, and the satellite and the gateway station 12 under test adopt high-frequency wireless communication at a feeding frequency, so the connection between the tester 11 and the gateway station 12 under test is The uplink wired connection between them can pass through an upconverter, so as to convert the intermediate freque...

Abstract

The present application provides a gateway station demodulation performance analysis method, device, system and storage medium. By establishing a radio resource control connection with the gateway station under test, the tester can send the jammed test packet to the gateway station under test, and receive the jammed test packet returned by the gateway station under test through demodulation and modulation. response packet. In this way, the tester can simply and conveniently analyze the demodulation performance of the gateway station under test by comparing the generated test packet and response packet, which greatly reduces the complexity of test analysis compared with spectrum analysis.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, relates to a gateway station demodulation performance analysis method, device, system and storage medium. Background technique [0002] The gateway station and the satellite use radio signal communication on the feeder link, and the communication frequency is divided into uplink and downlink directions. The uplink is the direction of the signal from the satellite to the gateway station, and vice versa is the downlink direction. Due to the long transmission distance between the gateway station and the satellite, the interference on the signal transmission path is complicated, before the gateway station is put into practical use, it is necessary to test the ability of the gateway station to receive and demodulate uplink signals to detect Whether the uplink demodulation capability of the off-site to the interfered signal is qualified. [0003] At present, the ...
