[0062] The interference scenario in this specific embodiment is frequency domain interference at the transmitting end; specifically, in a wireless system, due to frequency domain resource allocation conflicts between different user terminals, or overlapping frequency domain resource allocations of different terminal users in the handover buffer, etc. Cause Frequency domain interference is a common phenomenon. In this specific embodiment, the process of simulating the frequency domain interference at the transmitting end is as follows:
[0063] S1. The configuration unit configures corresponding interference parameters according to the frequency domain interference model, specifically, frequency domain resource overlap ratio parameters, frequency domain interference power amplitude, etc.;

[0072] The interference scenario in this specific embodiment is Gaussian white noise interference in the time domain of the 5G-ATG transmitter. Specifically, in the 5G ground-air interconnection system, due to the large coverage radius, the data at the transmitter is transmitted over a long distance, and the signal is interfered The attenuation is very large; therefore, 5G-ATG as a terminal device must pass the interference test of the field environment before commercial deployment; among them. It is a common interference scenario that the data sent by the ATG terminal is interfered by Gaussian white noise generated by long-distance spatial transmission through the air interface and wireless channel. In this interference scenario, the time-domain sample point data at the sending end will be superimposed and interfered by random noise sample point data. image 3 It is a schematic diagram of the time-domain Gaussian white noise interference simulation at the transmitting end pro...
