A data receiver, wherein the data receiver is configured to receive a signal, the signal comprising at least two separate partial data packets, wherein the at least two separate partial data packets comprise symbols which map encoded bits resulting from a redundancy-introducing encoding of a data bit sequence performed jointly for the at least two separate partial data packets, wherein the data receiver is configured to estimate a channel state of a transmission channel of the signal based on the received signal to obtain first channel state information, wherein the data receiver is configured to demodulate a first set of received symbols from different partial data packets using the first channel state information, wherein the first set of received symbols is a real subset of the received symbols of the at least two partial data packets to obtain a first set of received encoded bits, wherein the first set of received encoded bits allows drawing conclusions as to a first set of encoded bits corresponding on the transmitter side to the first set of received encoded bits, using the transmitter-side redundancy-introducing encoding, wherein the data receiver is configured to decode the first set of received encoded bits to determine, using the transmitter-side redundancy-introducing encoding, a first set of estimated encoded bits, which corresponds to a first set of transmitted encoded bits with higher probability than the received encoded bits, and to map the first set of estimated encoded bits to estimated transmission symbols using a mapping rule matching with a transmitter-side mapping rule to obtain a first set of estimated transmission symbols; wherein the data receiver is configured to determine second channel state information using the first set of estimated transmission symbols; wherein the data receiver is configured to demodulate a second set of received symbols from different partial data packets using the second channel state information, wherein the second set of received symbols is a real subset of the received symbols of the at least two partial data packets to obtain a second set of received encoded bits; wherein the second set of received symbols in the respective partial data packets comprises a greater temporal spacing to pilot symbols of the at least two partial data packets than the first set of received symbols. wherein the data receiver is configured to receive a signal, the signal comprising at least two separate partial data packets, wherein the at least two separate partial data packets comprise symbols which map encoded bits resulting from a redundancy-introducing encoding of a data bit sequence performed jointly for the at least two separate partial data packets, wherein the data receiver is configured to estimate a channel state of a transmission channel of the signal based on the received signal to obtain first channel state information, wherein the data receiver is configured to demodulate a first set of received symbols from different partial data packets using the first channel state information, wherein the first set of received symbols is a real subset of the received symbols of the at least two partial data packets to obtain a first set of received encoded bits, wherein the first set of received encoded bits allows drawing conclusions as to a first set of encoded bits corresponding on the transmitter side to the first set of received encoded bits, using the transmitter-side redundancy-introducing encoding, wherein the data receiver is configured to decode the first set of received encoded bits to determine, using the transmitter-side redundancy-introducing encoding, a first set of estimated encoded bits, which corresponds to a first set of transmitted encoded bits with higher probability than the received encoded bits, and to map the first set of estimated encoded bits to estimated transmission symbols using a mapping rule matching with a transmitter-side mapping rule to obtain a first set of estimated transmission symbols; wherein the data receiver is configured to determine second channel state information using the first set of estimated transmission symbols; wherein the data receiver is configured to demodulate a second set of received symbols from different partial data packets using the second channel state information, wherein the second set of received symbols is a real subset of the received symbols of the at least two partial data packets to obtain a second set of received encoded bits; wherein the second set of received symbols in the respective partial data packets comprises a greater temporal spacing to pilot symbols of the at least two partial data packets than the first set of received symbols.
