-
A.
SC-FDMA
chosen
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.
-
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.
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.
FDMA
FDMA is Japan’s national agency responsible for coordinating fire services, emergency medical response, and disaster management across the country.
-
E.
TD-SCDMA
TD-SCDMA is a 3G mobile telecommunications standard developed in China that uses time-division duplexing and code division multiple access to provide wireless voice and data services.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
