Communication SystemsError Control

Forward error correction (FEC) differs from basic ARQ because FEC aims to?

  • ACorrect errors at the receiver without requiring retransmission for each correctable error
  • BEliminate all redundancy
  • COperate only on analog AM signals
  • DMake channel noise exactly zero
Report an error
Correct Answer: A. Correct errors at the receiver without requiring retransmission for each correctable error
Explanation: FEC adds sufficient coding redundancy for the receiver to correct specified error patterns without requesting retransmission.
Reference: Standard communication systems: forward error correction
