A method of transmitting a communication signal and electric power between two user stations of a bus system includes coupling the communication signal into a bus line via a low-pass filter that filters the communication signal, such that signal frequencies below a cut-off frequency of the low-pass filter are coupled into the bus line of the bus system. The method also includes coupling, using a power coupling device, electric power in the form of a high-frequency signal into the bus line, transmitting the communication signal and the electric power as a bus signal to an electrical load using the bus line, and decoupling the communication signal from the bus line via a low-pass filter that filters the bus signal, such that signal frequencies below the cut-off frequency of the low-pass filter are decoupled from the bus line of the bus system.

Apparatuses and methods for transmitting a communication signal and electric power between two user stations of a bus system

A user station for a bus system and a method for improving a reception quality of messages in a user station of a bus system are provided. The user station includes an estimation device for estimating a channel impulse response when and/or after only one further user station of the bus system transmits a message to the bus system, or for determining necessary functions of filters directly from a signal received by the user station, and a correction device for correcting a signal received by the user station based on the channel impulse response estimated by the estimation device.

Device and method for improving the reception quality of messages in a CAN bus system

A user station for a bus system and a method for broadband CAN communication are provided. The user station includes a control unit for controlling an access of the user station via a first bus system to a bus of a second bus system of the communication system, the first bus system being designed for a communication, in which at least at times an exclusive, collision-free access of one of at least two user stations of the communication system to a bus of the first bus system is ensured, and the bus of the second bus system having at least two channels, via which it is possible to transmit messages of the at least two user stations of the communication system in different separate frequency ranges temporally independently of one another.

User station for a communication system and method for high-data rate CAN-based communication

A user station for a bus system and a method for the wideband communication in a bus system are provided. The user station includes a communications-control unit for preparing or reading at least one message for/from at least one further user station of the bus system, in which an exclusive, collision-free access of a user station to a bus line of the bus system is ensured at least intermittently; the communications-control unit is designed to prepare channel-status information according to a time sequence for the transmission specified in the bus system for the user station so that the user station does not have to send the channel-state information in each message, and the channel-status information includes information for ascertaining the channel characteristic between the user station and the further user station of the bus system to which the message is to be sent.

User station for a bus system and method for the wideband can communication

A user station is provided for connecting to a bus line and a method for compensating for an interference due to a CAN bus system in a received signal. A signal of a CAN bus system is transmitted via the bus line in coexistence with a signal of a further bus system. The user station includes a receiving unit for receiving an overall signal and for compensating for an interference in the received overall signal which occurs due to a changing output impedance of a user station of the CAN bus system which is connected to the bus line.

Parallel operation of a bus system and a can bus system having a device for compensating for interferences

A subscriber station for a bus system, and a method for improving the error tolerance of a subscriber station of a bus system, are presented. The subscriber station encompasses a transmission/reception device for transmitting a signal via the bus system to a further subscriber station and for receiving a signal via the bus system, in which exclusive, collision-free access by a subscriber station to a bus line of the bus system is guaranteed at least at times; and a modification device for modifying the transmission properties of a transmission path of the transmission/reception device and/or the reception properties of a reception path of the transmission/reception device.

Subscriber station for a bus system and method for improving the error tolerance of a subscriber station of a bus system

A user station for a bus system and a method for broadband CAN communication are provided, in which the user station includes a pulse shaping device for shaping the pulse of a message so that the message includes a training sequence which includes pieces of information for determining the channel characteristic between the user station and a further user station of the bus system to which the message is to be transmitted, and/or a correction device for correcting a signal received by the user station based on a training sequence, which is included in a message shaped by a pulse shaping device of the further user station.

Subscriber station for a bus system, and method for wideband can communication

A user station for a bus system implementing broadband CAN communication includes: a communication control device for creating or reading at least one message for/from at least one further user station of the bus system, in which exclusive, collision-free access of a user station to a bus of the bus system is ensured at least intermittently; and a data interleaving device for interleaving data packets of at least two messages into a single message, so that the data packets are situated in one data segment of the single message. The single message has a shared outer frame header for the data packets in front of the data segment and a shared outer frame end for the data packets after the data segment.

Subscriber station for a bus system and method for broadband can communication

A method for monitoring a communication network, which includes a plurality of processing units which communicate with one another via a communication medium, a channel of the communication medium being measured using channel estimation; from a result of the channel estimation, a characteristic variable being produced; and, with the aid of the characteristic variable, a decision is made as to whether a manipulative change of the communication network has occurred.

Method for monitoring a communication network

A method for acquiring at least one signal transmitted via an electric conductor, wherein an electric and/or magnetic field of the conductor is acquired at at least two identical or different positions relative to a longitudinal coordinate of the conductor, thus obtaining two measurement signals corresponding to the respective positions, and the signal transmitted via the conductor is inferred from the measurement signals.

Method and device for acquiring at least one signal

Concept for transmitting payload data from a transmitter to a receiver via a communication channel within a time interval, wherein channel-coded data packets are generated from the payload data, wherein each of the channel-coded data packets has packet core data corresponding to a packet identification of the respective channel-coded data packet, and wherein the packet core data is coded with a channel code of higher redundancy than the payload data. The channel-coded data packets are sent without any return channel to the receiver, which decodes packet core data of a first received channel-coded data packet of the time interval. If error-free decoding of the first channel-coded data packet fails, packet core data of at least one second received channel-coded data packet of the time interval are decoded to determine a suitable further channel-coded data packet for combination with the first channel-coded data packet to acquire, on account of the combination, an increased code gain for decoding of the payload data.
