<p>To detect a wanted signal in additive noise, the expected signal-to-noise ratio of the signal is measured over a time slot, the estimated white noise only is measured over another time slot without a wanted signal, the average energie of the noise and the signal with noise is measured in respective time slots, the theoretical detection threshold and the ratio between the two energy levels are calculated, and the ratio is compared to the calculated threshold, said threshold being greater than 1 (ideal threshold).</p> |
