Detection of weak signals using adaptive stochastic resonance

  title={Detection of weak signals using adaptive stochastic resonance},
  author={A. S. Asdi and Ahmed H. Tewfik},
We present a novel nonlinear filtering approach for detecting weak signals in heavy noise from short d a t a records. Such detection problems arise in many applications induding communications, radar, sonar, medical imaging, s e i s mology, industrial measurements, etc. The performance of a matched filter detector of a weak signal i n heavy noise is directly proportional to the observation time. We discuss an alternative detection approach tha t relies on a nonlinear filtering of the input… CONTINUE READING
