With ________ it is possible to simultaneously transmit either from or to different users by allocating the subcarriers during any one-time interval to multiple users.
A)OFDMA
B)SC-FDMA
C)SC-TDMA
D)all of the above

Question

Quizplus · Accepted Answer

OFDMA (Orthogonal Frequency Division Multiple Access) enables multiple users to simultaneously transmit or receive data by dividing a single transmission channel into multiple subcarriers. These subcarriers can be allocated to different users during any given time interval, ensuring that multiple users can transmit or receive data simultaneously without interference. SC-FDMA and SC-TDMA are also multiple access techniques, but they are not capable of allocating subcarriers to multiple users simultaneously. Therefore, only OFDMA is the correct answer.
