Question

Quizplus · Accepted Answer

The relationship among the subcarriers in the OFDM scheme is referred to as orthogonality. This means that the subcarriers are orthogonal or perpendicular to each other, which allows multiple signals to be transmitted simultaneously without interfering with each other. The other options, modulation, subchannels, and spread spectrum, do not accurately describe the relationship among the subcarriers in OFDM.
