This is an IEEE 802.11 OFDM modulator module, the implementation is based on 18.3.5.8 Subcarrier modulation mapping section in IEEE 802.11-2012 Std.

It has only one parameter: the subcarrier modulation, in compliant mode, is one of the following constellation mappings (Table 18-7.):

• BPSK
• QPSK
• 16-QAM
• 64-QAM

However, it can be used with an arbitrary OFDM compatible constellation mapping.
