Assume that the signal does not have any features like pilot tones, cyclostationary features etc. For example, samples drawn independently and identically from a given zero-mean signal constellation satisfy this assumption. On possible metric to measure the performance of a detector is its sample complexity, defined as the number of … text/html 2008-09-15T17:06:57-08:00 Rahul Tandra http://wifo.eecs.berkeley.edu/wiki/doku.php/cognitivehistory:snr_walls_using_worst-case_uncertainty?rev=1221523617&do=diff SNR Walls using Worst-case Uncertainty Idea Description Consider the problem of robustly detecting the presence/absence of a signal in the presence of noise. In any real system modeling uncertainties are unavoidable. So, we assume that the distribution of the noise process is uncertain and that it lies within a given bounded uncertainty set. We measure the performance of a detection algorithm by the worst-case probability of false-alarm and worst-case probability of mis-detection, where the wo…
