ANTENNA DEVICE AND METHOD FOR PRECODING DATA IN A MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM
摘要
An antenna device and method for precoding data in a MIMO system. The antenna device comprises a plurality of physical antennas in a distributed antenna system and a MIMO precoder. The MIMO precoder has a plurality of inputs for a plurality of data streams and a plurality of outputs for the plurality of data streams. A second precoder is disposed in series with the MIMO precoder. The second precoder maps a data stream to an output associated with a physical antenna port associated with at least one of the plurality of physical antennas.
