Target entity: Frequency Division Duplex Context triple: [FDD, fullName, Frequency Division Duplex]
-
A.
OFDMA
OFDMA (Orthogonal Frequency Division Multiple Access) is a multi-user version of OFDM that divides subcarriers among multiple users to enable efficient, high-capacity wireless communication in systems like LTE and WiMAX.
-
B.
SC-FDMA
SC-FDMA (Single-Carrier Frequency Division Multiple Access) is a multi-carrier transmission scheme used primarily in LTE uplink that combines single-carrier characteristics with frequency-domain equalization to achieve lower peak-to-average power ratio than OFDM.
-
C.
OFDM
OFDM (Orthogonal Frequency-Division Multiplexing) is a digital multi-carrier modulation technique that splits data across many closely spaced orthogonal subcarriers to improve robustness against interference and multipath fading in wireless and wired communication systems.
-
D.
Time Division Multiple Access
Time Division Multiple Access (TDMA) is a channel access method that divides a communication medium into time slots so multiple users can share the same frequency without interference.
-
E.
FDD
chosen
FDD (Frequency Division Duplex) is a communication method that separates uplink and downlink signals onto different frequency bands to enable simultaneous two-way wireless transmission.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
