Best answer
Correct choice is (b) Probability of detection and probability of false alarm

Best explanation: Probability of detection and probability of false alarm are factors of significance in energy detection technique. They depend on the signal to noise ratio, time-bandwidth product, complete and incomplete gamma functions, and generalized Marcum Q-function.
