Definition of the formal semantics of control state diagrams and implementation of a graphical editor
Abschlussarbeit (Master; Diplom)(Universität Ulm, 2018-06-08)Abstract State Machines (ASM) are a formal specification language which is used in the software and system engineering. Different to UML2 diagrams, which are another well-known, graphical, formal specification language, ... -
Automotive radar interference mitigation using a sparse sampling approach
Beitrag zu einer Konferenz(Universität Ulm, 2017)The application of radar sensors for driver assistance systems and autonomous driving leads to an increasing probability of radar interferences. Those interferences degrade the detection capabilities and can cause sensor ... -
Estimation and cancellation of interferences in automotive radar signals
Beitrag zu einer Konferenz(Universität Ulm, 2017)Radar sensors become typical components for automotive driver assistance systems and autonomous driving. The widespread use of this sensor type leads to an increasing risk of unwanted interferences. Those interferences ... -
Analytical and experimental investigation on mitigation of interference in a DBF MIMO radar
Wissenschaftlicher Artikel(Universität Ulm, 2017)As driver assistance systems and autonomous driving are on the rise, radar sensors become a common device for automobiles. The high sensor density leads to the occurrence of interference, which decreases the detection ... -
Compensation of motion-induced phase errors in TDM MIMO radars
Wissenschaftlicher Artikel(Universität Ulm, 2017)For high-resolution direction of arrival estimation, a wide aperture is necessary. This can be achieved with multiple-input multiple-output (MIMO) radars, which offer a wide virtual aperture. However, the requirement of ... -
A debating ontology for argumentative dialogue systems
Abschlussarbeit (Bachelor)(Universität Ulm, 2018-06-01)This thesis designs and implements an ontology which encodes the argumentative structure of natural language debates. This Debating Ontology will constitute the database for a prospective Argumentative Dialogue System, ... -
Interference of chirp sequence radars by OFDM radars at 77 GHz
Beitrag zu einer Konferenz(Universität Ulm, 2017-05-04)Radar sensors are common devices in daily traffic, especially for driver assistance and automotive safety systems. A high sensor density increases the probability of interferences, especially when the sensors occupy a large ... -
Reflection reduction through modal filtering for integrated antenna measurements above 100 GHz
Wissenschaftlicher Artikel(Universität Ulm, 2017)Feeding integrated antennas during a measurement requires special feeding structures. Due to the small antenna dimensions, these feeding structures are often much bigger than the antenna under test (AUT) itself and with ... -
Digital beamforming to mitigate automotive radar interference
Beitrag zu einer Konferenz(Universität Ulm, 2016)Interference between automotive radars decreases the sensors’ detection capabilities. It is possible to use digital beamforming (DBF) in multi-antenna systems to reduce the power received from certain directions of ... -
Bats-inspired frequency hopping for mitigation of interference between automotive radars
Beitrag zu einer Konferenz(Universität Ulm, 2016)It was reported for specific bats, that they use a certain scheme to shift the frequencies of their echo location calls to counteract interferences with conspecifics. As in road traffic, an increasing number of cars is ...
