Ieee80211OfdmModulator¶

Package: inet.physicallayer.wireless.ieee80211.bitlevel

simple module Ieee80211OfdmModulator

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

It has only one parameter: the subcarrier modulation, which, 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.
