DECODER-ASSISTED ITERATIVE CHANNEL ESTIMATION

Embodiments represent a data receiver, wherein the data receiver is designed for receiving a signal, wherein the signal has at least two separate sub-data-packets, wherein the at least two separate sub-data-packets have symbols mapping coded bits resulting from a coding of a data bit string carried out for the at least two separate sub-data-packets together and introducing a redundancy, wherein the data receiver is designed to estimate a channel status of a transmission channel of the signal based on the received signal, in order to obtain first channel status information, wherein the data receiver is designed to demodulate a first set of received symbols from different sub-data-packets using the first channel status information, wherein the first set of received symbols is an actual partial quantity of the received symbols of the at least two sub-data-packets in order to obtain a first set of received coded bits, wherein the first set of received coded bits permits an inference of a first set of coded bits corresponding to the first set of received coded bits on the transmission side, with the utilisation of the transmission-side redundancy-generating coding, wherein the data receiver is designed to decode the first set of received coded bits, to determine a first set of estimated coded bits, with the utilisation of the transmission-side redundancy-generating coding, which corresponds to a first set of transmitted coded bits with a higher level of probability than the received coded bits, and to map the first set of estimated bits as estimated transmission symbols using a mapping rule corresponding to a transmission-side mapping rule in order to obtain a first set of estimated transmission symbols, wherein the data receiver is designed to determine second channel status information using the first set of estimated transmission symbols. Des modes de réalisation de la présente invention concernent un récepteur de données ; le récepteur de données étant conçu pour recevoir un signal ; le signal comportant au moins deux paquets partiels de données séparés ; les au moins deux paquets partiels de données séparés comportant des symboles, lesquels représentent des bits codés, lesquels résultent d'un codage d'une séquence de bits de données introduisant une redondance mise en uvre ensemble pour les au moins deux paquets partiels de données séparés ; le récepteur de données étant conçu pour estimer, en fonction du signal reçu, un état de canal d'un canal de transmi
