technical field [0001] The present invention relates to the field of communication, in particular to the field of wireless communication systems, in particular to a modeling control method based on a computer software system for a basic fading model of a wireless channel. Background technique [0002] The performance of a wireless communication system is mainly determined by the wireless channel environment, and the understanding of wireless channels is a necessary prerequisite for designing wireless transmission technologies with high performance and high spectral efficiency. However, in the actual environment, wireless channels are dynamic and unpredictable, which brings problems such as large resource consumption and unrepeatable test results to field measurements. It is these problems that gave birth to the channel simulator.

Problems solved by technology

[0003] The traditional channel simulator modeling method is mainly to generate the required channel coefficients according to the configuration parameters and then send the coefficients to the hardware. The main disadvantage is that when the number of channels is large, it takes a long time to generate the coefficients. More than tens of minutes, and when the configuration parameters are changed, it is still necessary to wait for new channel coefficient generation
