  • In the face of wireless access needs with wide coverage under vertical industries like intelligent ocean and intelligent agriculture, low earth orbit (LEO) satellite communication has become an essential part of the next-generation mobile communication technology due to its reliable connectivity, wider coverage capability and great potential for wide band connection. There is still a lack of systematic channel modeling procedures and simulation methods for LEO mobile communications and the modeling of the highly dynamic characteristics of LEO satellite channels, also, only single scenario is considered in most up to date models. Based on this, it proposes a modular and highly dynamic satellite communication channel modeling mechanism with versatile scenarios in this paper, and accordingly designs and develops a dynamic satellite channel simulation system. The idea of process-oriented is realized in the proposed simulation system, also the dynamic update methods for wireless channel parameters in view of the dynamic feature of satellite channel is introduced. The channel model designed in this paper can obtain channel parameters and the channel impulse response of LEO satellite communication channel by means of simulation, and it also has good compatibility for different scenarios.
