SNR Walls for Signal Detection

  title={SNR Walls for Signal Detection},
  author={Rahul Tandra and Anant Sahai},
  journal={IEEE Journal of Selected Topics in Signal Processing},
This paper considers the detection of the presence/absence of signals in uncertain low SNR environments. Small modeling uncertainties are unavoidable in any practical system and so robustness to them is a fundamental performance metric. The impact of these modeling uncertainties can be quantified by the position of the "SNR wall" below which a detector will fail to be robust, no matter how long it can observe the channel. We propose simple mathematical models for the uncertainty in the noise… CONTINUE READING
