A physical layer (PHY) module includes NT radio frequency (RF) channels and a mapping module. The NT RF channels each include N subcarriers. The mapping module includes Ns inputs receiving corresponding ones of NS data streams. The mapping module further includes NT outputs communicating with corresponding ones of the NT RF channels. Each of the NT outputs includes N outputs. The mapping module further includes a mapping matrix that maps the NS data streams to the NT outputs. NT, NS, and N are integers greater than or equal to 2. The NT RF channels include NT gain modules that apply NT different complex gains to the NT outputs, respectively. One of the NT different complex gains is applied to each of the N outputs of a corresponding one of the NT outputs. The NT different complex gains correspond to NT transmit antennas of the NT RF channels, respectively.
