N2 - In certain scenarios higher-order statistic (H0S)-based detectors for non-Gaussian signals have been shown to have performances superior to widely-used second-order (SOS) techniques, owing to the HOS Gaussian noise rejection property. We study the effects of commonly-used narrowband processing on these detectors. As the processing bandwidth is decreased, we characterize the tradeoff between the HOS and SOS detectors and demonstrate that the performance of the HOS detector degrades faster than the SOS one. We then consider distributed wideband detection by a bank of L narrowband detectors whose decisions are fused together. We show that, given a fixed-bandwidth input signal, as L increases, the performance of the HOS distributed detector degrades faster than the SOS one.
