Wireless Communication Systems Design for Tactical Software-Defined Radios – From Scenario-Based Analysis to Channel and Waveform Parameter

Software defined radios and especially the associated digital waveforms for tactical wireless communication systems feature a high degree of freedom and can be tailored to completely different operational needs. In case of the development of new digital waveforms which can not be adopted from existing ones, methods for technical parameter definition have to be found. In this paper a method based on ‘scenario based analysis’ is presented which allows a technical parameter definition in dependency on operational needs. Exemplary this method is demonstrated for the definition of channel models and waveform parameters, the physical OSI layer (open systems interconnection reference model) of a communication system. Possible extensions of the method, e.g., for defining parameter of higher OSI layer are indicated. The work for this paper was motivated by current activities in civil and military sector.
