A data transmitter for transmitting a data packet to a data receiver via a communication channel includes a generator for generating the data packet and a transmitter for transmitting the data packet. The generator for generating the data packet is configured to generate a data packet having a first data block and a second data block and a predefined first reference sequence and second reference sequence for synchronizing the data receiver, wherein the first reference sequence is longer than the second reference sequence, and wherein in the data packet, the second data block is located between the first reference sequence and the second reference sequence, and the first reference sequence is located between the first data block and the second data block. The transmitter for transmitting the data packet is configured to transmit the data packet to the data receiver via the communication channel.

Data transmitter and data receiver

A transmitter for transmitting an output signal includes first and second filter structures. The first filter structure includes a first combiner to extend a first data signal by a first reference signal to obtain a first extended data signal, and a first IIR filter for filtering the first extended data signal to obtain a first filtered data signal. The second filter structure includes a second combiner to extend a second data signal by a second reference signal, and a second IIR filter for filtering the second extended data signal. The transmitter includes a multiplexer for combining the first and second filtered data signals to obtain the output signal. A system response of the first IIR filter based on the first reference signal corresponds to a system response of the second IIR filter based on the second reference signal.

Transmitting means for transmitting an output signal, receiving means for receiving an output signal, and methods for transmitting and receiving the same

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.
