Patent ID: 7372802

Claim:
A receiving device for receiving an overlaid receiving signal corresponding to a superposition of a first and a second transmitting signals, respectively, transmitted by a first transmitter and a second transmitter arranged remote from the first transmitter, wherein the first and the second transmitting signals lie in the same frequency band, wherein the first transmitting signal is generated, using a first transmitting subgroup of code units, wherein the second transmitting signal is generated using a second transmitting subgroup of code units, wherein the first transmitting subgroup of code units and the second transmitting subgroup of code units together represent a plurality of code units which were generated by a redundancy-adding encoding from an information word with a plurality of information units, comprising: a sampler for sampling the overlaid receiving signal synchronously to the first transmitter in order to obtain a first receiving signal associated with the transmitted first transmitting signal, and for sampling the overlaid receiving signal synchronously to the second transmitter in order to obtain a second receiving signal associated with the transmitted second transmitting signal; a decoder for decoding the first and the second receiving signal in order to obtain a first receiving subgroup of code units associated with the first transmitting subgroup of code units, and to decode the first and the second receiving signal in order to obtain a second receiving subgroup of code units associated with the second transmitting subgroup of code units; a calculator for calculating a first interference signal using the second receiving subgroup of code units and a second interference signal using the first receiving subgroup of code units; an interference reducer for combining the first interference signal with the first receiving signal and for combining the second interference signal with the second receiving signal in order to obtain an improved first receiving signal and an improved second receiving signal; and a controller for controlling the decoder so that the decoder decodes the improved first receiving signal and the improved second receiving signal and outputs the information word with the plurality of information units based on the improved first receiving signal and the improved second receiving signal.
