摘要: This paper presents a detector for cyclostationary signals that uses an estimate of spectral autocoherence as detection statistic. The detector's probability false alarm is analytically derived and verified with computer simulations. Receiver operating characteristic curves are determined from the simulation data analytical expression alarm. A polycyclic based on generalized coherence estimation also described but not analyzed.
