-
A.
Code Division Multiple Access
Code Division Multiple Access (CDMA) is a digital cellular technology that allows multiple users to share the same frequency band simultaneously by assigning unique codes to each user’s signal.
-
B.
OFDM
chosen
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.
-
C.
Frequency Division Multiple Access
Frequency Division Multiple Access (FDMA) is a channel access method in which the available bandwidth is divided into distinct frequency bands so multiple users can transmit simultaneously on different frequencies.
-
D.
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.
-
E.
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.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
