For coherent BPSK in AWGN, increasing Eb/N0 generally causes the bit error probability to?

  • AIncrease
  • BDecrease
  • CRemain exactly constant
  • DBecome greater than one
Report an error
Correct Answer: B. Decrease
Explanation: A larger energy-per-bit to noise-density ratio improves separation relative to noise, reducing coherent BPSK error probability.
