matlab - Is it possible that adding noise to a signal can increase detection possibility? -

-

i simulating feature detector in noisy environment consist of awgn noise , impulsive noise. getting strange result signal impulsive+awgn noise has better detection probability signal awgn. know wrong @ point. how possible signal more noise impulsive noise has better detection possibility. please share experience.

yes, possible in case of stochastic resonance (http://en.wikipedia.org/wiki/stochastic_resonance)
