Embodiments provide a receiver for receiving encoded data from a transmitter in a communication system having a plurality of transmitters, the receiver comprising a decoder having a demodulator configured to demodulate a received signal , to obtain a sequence of received symbols , at least a subset of received symbols of the received symbol sequence having information from transmissions from a plurality of transmitters, wherein the decoder is configured to reconstruct an encoded data bit sequence into which the data from the transmitter is coded based on the sequence of received symbols and based on error correcting bits corresponding to an error correction code with which the data is encoded, by, for each bit of the encoded data bit sequence, in a first part of an iteration step, determining a first probability information describing a reliability of the bit of the encoded data bit sequence given a corresponding received symbol of the sequence of received symbols, and determining a second probability information describing probabilities that the bit of the encoded data bit sequence fulfills corresponding error correcting bits of the error correcting code; in a second part of the iteration step, determining, based on the first probability information and the second probability information, a third probability information describing a probability that the current bit of the encoded data bit sequence corresponds to an actual bit of the encoded data bit sequence as transmitted by the transmitter.
