Short-Time Sample Robust Detection Study.

摘要

The optimum detector is well defined when the signal and noise characteristics are completely specified through deterministic and/or probabilistic statements. Unfortunately this is not always the case and attempts to make it so through assumptions of one sort or another may lead to poor detector performance. This report studies the detection problem when certain of the signal or noise properties are unknown except perhaps within some wide class. Particular attention is directed to communications problems characterized by small time-bandwidth signals. (Author)
