Abstract
A MIMO transmitter including a modulator, a demultiplexer arranged to divide the information into one or more demux streams for transmission over different ones of the channels, and a diversity splitter to derive one or more sub-streams of the same information. A decorrelator such as a scrambler decorrelates the sub-streams before or after the modulation. In use, the arrangement is configurable to vary a ratio of demultiplexing and of diversity splitting. This balances between the gains from diversity and spatial multiplexing, without needing major changes to the transmit and receive processing.
