The disclosure relates to a method and a control device for data-optimized control of a driving maneuver. The method comprises several procedural steps. The following takes place: - Acquisition of sensor data from a large number of sensor units in the vehicle; - Providing the acquired sensor data at a reduced data rate as preliminary sensor data to a central control device; - Evaluating the provided preliminary sensor data in the central control device; - Dynamic adjustment of the vehicle's data transmission rate based on the current driving situation of the vehicle and the functional requirements of a driving maneuver to be executed, whereby the data transmission rate is varied in different phases of the driving maneuver in order to aim for a level of detail in the sensor data adapted to the relevance of the driving situation and / or the driving maneuver; - Executing the driving maneuver based on the acquired sensor data, using detailed sensor data with a high data rate in maneuver phases with high data relevance and sensor data with a lower data rate in maneuver phases with low data relevance; and - Providing control information to the motor vehicle to execute the driving maneuver.

Methods, devices, and system for Enhanced Wideband HF data transmission with adaptive interference avoidance and other improvements. Several embodiments describe a mesh network comprising a plurality of transmitting and receiving nodes in a congested band. The network senses the interference spectrum occupancies at a plurality of receiver nodes and synthesizes transmit waveforms at the transmit nodes so that the spectra of the transmit signals fit into the gaps of the interference spectra at the receiver nodes. The waveform is based on FDM, including OFDM, with adaptive tone suppression at the transmitter. The spectrum occupancy information at each node is continually shared in the background among all nodes using a low data rate, Fountain code with erasure sensing at the receivers, which guarantees robust delivery.

A computer system for offloading sensor data processing is disclosed. An aggregation processor circuit may receive multiple data streams from corresponding ones of multiple sensors included in the computer system. The aggregation processor circuit may send a first portion of a particular data stream of the multiple data streams to a primary memory circuit for storage, and send a second portion of the particular data stream to a secondary memory circuit. The aggregation processor circuit may send the second portion of the particular data stream at a lower data rate than the first portion of the particular data stream.
