Abstract: A method of decoding multiple transmissions of time related data is provided. The method comprises receiving and recognizing separate data blocks, each data bock having data that comprises at least a code word assigned to a system frame number that depends on the transmission time of the respective data block; demodulating each data block in order to obtain IQ-samples, likelihood ratios or representatives thereof for each data block; accumulating the IQ-samples, likelihood ratios or representatives thereof to a sum that is forwarded to a single-block decoder; and decoding the sum, thereby obtaining decoding results. Further, a device for decoding multiple transmissions of time related data as well as a method of verifying a device for decoding multiple transmissions of time related data are described.
