Abstract: The present disclosure relates to a dirty paper coding (DPC) scheme for a wireless communication system. One example encoding device obtains symbol probabilities for symbols of a symbol sequence given an effective interference based on a target distribution of symbols of a transmit signal, encodes a message into the symbol sequence based on the symbol probabilities, and then obtains the transmit signal based on a mapping of the symbol sequence and the effective interference using a scalar function. One example decoding device obtains a receive signal, obtains a symbol sequence based on the receive signal and a scaling factor using a scalar function, and then decodes the symbol sequence to obtain a message.
