Transmitting device and receiving device

摘要

In a transmitting/receiving concept a redundancy-adding encoder with a code rate larger or equal 0.5 is used in order to obtain two data streams for two different transmitters which are arranged at spatially different positions. Both transmitters transmit in the same frequency band. 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 in order 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 which are transmitting in the same frequency band, however. The receiver concept shows a quick convergence and thus enables the two transmitters to transmit in the same frequency band, which results in a reduction of the required bandwidth by half compared to a corresponding transmitter concept in which the first and the second transmitters transmit at different frequencies.
