ABSTRACT:
The invention proposes for improving the overall spectral efficiency of wireless telecommunication systems, in particular of mobile communication systems, the transmission of at least one multiframe signal having a plurality of sub-frames with predefined logical channels (BCCH, FCCH, SCH) repeatedly embedded in predefined sub-frames, wherein a transmitter diversity is applied using antenna and/or polarization hopping sequences such that during the transmission of respective one multiframe, each logical channel (BCCH, FCCH, SCH) is transmitted at least two times with a different antenna and/or polarization.
