Claim of US Patent No. 10,462,843

1. A method for digital transmission of data blocks froma transmitting station to a receiving station, the method comprising:
providing the data blocks with error protection data at the transmitting station, wherein the error protection is transmitted via a faulty transmission channel to the receiving station, wherein, for transmission of at least one further data block, positions at which the further data block differs from a preceding data block are identified at the transmitting station, wherein delta information obtained in this way is provided with corresponding error protection;
adding the delta information with error protection to the at least one further data block provided with error protection to provide an augmented further data block, wherein the delta information is provided with a higher error protection than the at least one further data block;
transmitting the resulting augmented further data block via the faulty transmission channel to the receiving station;
storing the received preceding data block and the at least one augmented further data block, including the error protection component, in the receiving station;
retrieving the delta information of the at least one augmented further data block;
applying the delta information to the stored preceding data block to change the stored preceding data block into a transformed received preceding data block that is in a form comparable with the at least one further data block, wherein the applying of the delta information changes the stored preceding data block into an information block which corresponds to information content of the at least one further block for subsequent processing through soft combining;
soft combining the received at least one further data block and the transformed received preceding data block to produce a combined data block; and
retrieving a payload of the at least one further data block from the combined data block.
