Abstract:
1. A receiver for decoding a receive signal in a wireless communication system, comprising: a signal determiner configured to determine a complex receive value for the receive signal; a soft information determiner configured to acquire a soft information represented by a combination of a first probability value and a second probability value, wherein the first probability value is derivable by adding a value depending on an overall probability density function for each symbol of a modulation alphabet comprising a same first bit value at a same bit position of the symbols, wherein each symbol of the modulation alphabet represents at least two bits, wherein the overall probability density function indicates a probability of receiving the complex receive value, if a signal representing the respective symbol considered for adding was transmitted from a transmitter to a relay station, wherein the signal representing the respective symbol is caused by the receive signal received from the relay station, wherein the second probability value is derivable by adding a value depending on the overall probability density function for each symbol of the modulation alphabet comprising a same second bit value at the same bit position of the symbols, wherein the first bit value and the second bit value are different; a soft information decoder configured to decode payload data comprised by the receive signal based on the acquired soft information.
