[STDS-802-16-MOBILE] Mapping of STC data in optional FUSC and normal FUSC zones
Is the mapping order for STC coded bursts the same for 'Optional
AMC/Optional FUSC' and FUSC?
In case of 'Optional AMC/Optional FUSC' the mapping of data subcarriers
seems to be done in pairs
of symbols.
i.e. For 2 antanna STC matrix A, if S1 to S4 are four consecutive data
symbols,
S1 would be mapped to symbol 1 antanna 0 and -conj(S2) would be mapped to
symbol 2 antanna 0.
S3 would be mapped to symbol 1 antanna 0 and -conj(S4) would be mapped to
symbol 2 antanna 0.
Therefore S1 and S2 belong to the same slot.
In case of normal FUSC as specified in corr1_D3, S1 two data subcarriers
from adjacent symbols are
STC encoded.
Therefore if the data mapping remains the same as non-STC encoded bursts,
this would mean that
S1 would be mapped to symbol 1 antanna 0 and -conj(SN) would be mapped to
symbol 2 antanna 0.
Where S1 and SN do not belong to different adjacent time slots. This
assumption however does
not seem consistent with Matrix B horizontal encoding where S1 and SN belong
to two separate
bursts.
Could someone please clarify this.
