KOM | Communication Systems

The Communication Systems (KOM) department conducts conceptual and experimental research on communication systems. Focal points are the efficient use of communication channels, solutions for reconnaissance and surveillance as well as jamming of radio links. These topics are seen within tactical deployment scenarios in a multinational environments. The Bundeswehr requirements arise from networked operational command and control in such scenarios are the jumping-off point of our work. 

Based on long term experiences the department evaluates communication systems regarding aspects of security, reliability, and mobility across all OSI layers of the network protocol architecture. The knowledge gained by these evaluations is used to optimize these protocols for mobile tactical communication. This allows for the design of rapidly deployable communication systems. It leads to information technology superiority as well as enhanced military capabilities in command and control as well as signals intelligence. 

With its research groups »Robust Heterogeneous Networks«, »Software Defined Radio« and »Reconnaissance and Jamming« the department supports the Bundeswehr and civil security authorities in performing sovereign tasks. This is achieved in particular through specific consulting activities and the contribution of findings to various national and international standardization and development projects.

Reconnaissance and jamming of communication signals

The »Reconnaissance and Jamming« research group considers the aspects of signal intelligence and jamming of radio communication signals. Algorithms and systems for single and multi-channel analysis of broadband and narrow band interception signals are developed. They are integrated into powerful, functional clusters. The focal points are on radio and audio signals, smart antennas and the determination of radio wave propagation including potential interference with radio transmissions. One of the group’s strengths is the development of technology in close collaboration with the users.

 

Next-generation tactical radio procedures

The »Software Defined Radio« research group contributes to the development and standardization of modern network-enabled radio procedures for tactical applications. The focus is on waveforms for coalition wide use. A guiding directive is »Interoperability through Portability«. Thus the group not only contributes to technical specifications. Strong emphasis is put on the efficient implementation as waveform application for software defined radios. Future technologies such as cognitive radio and full-duplex radio are further subjects of research.

 

Secure information transmission

The »Robust Heterogeneous Networks« research group works on secure IP-based information transmission in heterogeneous networks. Covering various aspects concepts and technologies for end-to-end communication as well as civil and military standards are developed. The integration of information from tactical networks is crucial for network-centric operations management. Specific communication solutions are abstracted on robust internet protocol components. This enables seamless integration of systems and concepts of end-to-end communication for security and mobility, especially for operation in networks.
