ABSTRACT:
A physical layer module includes a mapping module and a plurality of gain modules. The mapping module maps a plurality of coded data streams to a plurality of transmit antennas, in which each transmit antenna is associated with a respective radio frequency channel of a plurality of radio frequency channels. Each gain module is associated with a respective radio frequency channel of the plurality of radio frequency channels, and is configured to apply a complex gain to the coded data stream mapped to the respective radio frequency channel associated with the gain module. The complex gain applied by the gain module differs relative to that applied by other gain modules, and corresponds to the transmit antenna associated with the respective radio frequency channel.
