Abstract

The present invention relates to a data transmission network, in particular a single frequency network (SFN), comprising a space-time block code (STBC) encoder for encoding user data of a user data stream into channel symbols of two or more channel data streams for transmission and a plurality of transmitters in a transmission area for transmitting said channel data streams using the same frequency channel for reception by one or more receivers located in said transmission area, wherein the number of transmitters is larger than the number of channel data streams and wherein each channel data stream is transmitted by at least one transmitter. To enable the deployment of STBCs in an SFN and a uniform gain in the coverage area of the SFN the data transmission network further comprises control means for controlling, which channel data stream is transmitted by which transmitter, such that all channel data streams are simultaneously transmitted, that at least two transmitters are transmitting the same channel data stream and that at least one transmitter is changing which channel data stream it transmits.
