[0003] Before the present invention, the simulation of existing satellite communication is generally based on the simulation system, which can produce satellite channels that meet the experimental requirements, but the structure is not completely materialized, the whole system is huge and complex, difficult to realize, and the function is single, or Only a single satellite channel can be generated, and the complex network structure of satellite communication cannot be simulated, or only focus on the construction of communication links, ignoring the importance of channel simulation, and the influence of channel characteristics and network topology on communication performance cannot be ignored. Existing equipment or systems usually require multiple sets of interconnections, which increases the complexity of the system

The invention discloses a satellite communication system simulator. The device can simulate the real channel delay error code characteristic and has a system networking function. The simulator comprises a receiving unit, a link unit, a channel unit, a sending unit, a channel control unit, a networking control unit and a statistic module. The simulator is used for simulating an actual satellite communication process and focuses on the research of delay and error code characteristic in the communication process, and the influence of a network topology on communication quality. Compared with the prior art, the simulator has the advantages that a satellite simulation channel is generated, a network structure is established systematically, the integration degree is high and the operation is simple.
Description
technical field [0001] The invention belongs to the technical field of satellite communication, and relates to a satellite communication system simulator, in particular to a device capable of simulating real channel delay error characteristics and having a system networking function, which provides support for satellite communication experiments. Background technique [0002] Satellite communication is a communication method that realizes radio transmission between ground and space users through the relay of artificial earth satellites. It has the characteristics of wide coverage and stable channels. The satellite communication system simulator can generate a channel model with actual characteristics to realize the channel transmission of data signals, so that the satellite communication process can be simulated in the test environment. The generation of the channel model and the control of the network structure are important components of the satellite communication simulat...
