ABSTRACT:
In a transmitting/receiving concept a redundancy-adding encoder is used in order to obtain two data streams for different transmitters. In the receiver, the receiving signal is sampled by a first sampler synchronous to the first transmitter and is output by a second sampler synchronous to the second transmitter in order to obtain a first and a second receiving signal which are fed to a trellis decoder to obtain a decoded first and second receiving subgroup of code units which are again fed to a calculating means in order to calculate the interference signals which are then combined with the corresponding receiving signals for an interference reduction. The iterative concept enables an interference reduction for receiving signal generated by two spatially separated transmitters. The receiver concept shows a quick convergence and thus enables the two transmitters to transmit in the same frequency band.
