Abstract
The report examines the problem of detecting signals consisting of harmonically related and partially correlated components. FFT based detection algorithms that utilize this structure to enhance detection performance are investigated. Two basic detection algorithms are considered. In the case of "coherent" detector, spectral components corresponding to harmonic frequencies are first combined, and then the resulting expression to estimate total signal power are used. Such an approach stands in contrast to an "incoherent" detector which is a generalization of conventional detectors and is based on the principle of independently estimating the power at each harmonic frequency bin. Statistical laws governing these detection algorithms are delineated and theoretical and simulation results are presented. The report concludes that harmonic detector structures are inherently superior in their performance to single-bin detectors.
