Concurrent development and verification of an all-software baseband for satellite ground operations

摘要

Communication systems are adopting all-software architectures, because of their scalability, extensibility, flexibility, and cost-effectiveness. This paper introduces a concurrent approach to the development and verification of baseband systems for satellite ground operations based on the behaviour-driven development methodology. The open-source GNU Radio development kit is used for developing the software-defined radio baseband signal processing, as well as simulating the satellite and realistic channel impairments. The system performance at the end shows deviations of less than 1 dB with respect to the ideal performance and the Green Book standards specified by the Consultative Committee for Space Data Systems.
