How does OFDMA differ from OFDM?

The correct answer is C. OFDMA allows multiple devices to transmit simultaneously on the same frequency. OFDM (Orthogonal Frequency-Division Multiplexing): Divides a channel into multiple subcarriers for data transmission. OFDMA (Orthogonal Frequency-Division Multiple Access): Extends OFDM by allowing multiple users to share subcarriers simultaneously, improving efficiency and…
