Table 6 Constellation parameters
The 4D-TCM provides the a k and Δ bk
values to the ADPSK Modulator according to the bit-loading table. If
the bit-loading table indicates that a subcarrier does not carry any information (0 bits per subcarrier) this
subcarrier shall be modulated using 2 bits.
3.7 OFDM MODULATION
This section describes how the input constellations are grouped to create OFDM symbols. Special symbols for
synchronization and SOT are also described.
The signals will be described in a complex base-band signal notation. Different implementations may be
possible, if the signal transmitted to the channel is the same.
