How does OFDMA differ from OFDM?

Question

Options

• ASubcarriers of OFDMA can contain data destined for a different receiver
• BOFDMA offers greater range by using multiple channels at once
• COFDMA allows multiple devices to transmit simultaneously on the same frequency
• DOFDMA uses multiple radios to achieve higher throughput

• A
  4% (1)
• B
  4% (1)
• C
  84% (21)
• D
  8% (2)

Explanation

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 spectral utilization.
