1 results about "Channel impairments" patented technology

The application discloses a kind of satellite communication system test method, test system and electronic equipment.The application is successfully solved the conflict problem of multiple virtual users sharing single radio channel by virtualizing multiple independent running terminal instances on single physical terminal hardware and with the aid of preset unified back channel resource and time slot conflict arbitration mechanism, to realize the multiple user concurrent test of satellite communication system using real hardware.The method not only covers the complete signal link from the primary station modem radio frequency front end to the high layer protocol processing node, ensures the high confidence and authenticity of test results, but also can be compatible with the introduction of real channel impairment environment, while greatly reducing the cost and complexity of a large number of hardware equipment required by traditional multi-user test, to realize efficient, high-fidelity end-to-end system verification.
