摘要
A physical layer device including a mapping module to map a plurality of data streams to a plurality of transmit antennas. Each transmit antenna is associated with a respective radio frequency channel. A first gain module communicates with a first transmit antenna, receives a first plurality of signals generated based on the plurality of data streams, and applies a first complex gain corresponding to the first transmit antenna to each of the first plurality of signals. A second gain module communicates with a second transmit antenna, receives a second plurality of signals generated based on the plurality of data streams, and applies a second complex gain corresponding to the second transmit antenna to each of the second plurality of signals. The second plurality of signals is different than the first plurality of signals. The second complex gain is different than the first complex gain.
