-
A.
Frequency Division Duplex
Frequency Division Duplex is a communication method in which uplink and downlink transmissions occur simultaneously on separate frequency bands, commonly used in cellular and wireless networks.
-
B.
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.
-
C.
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.
-
D.
Time Division Duplex
Time Division Duplex is a wireless communication method that uses a single frequency band for both uplink and downlink by separating them in time rather than frequency.
-
E.
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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
