ARL-TR-8271 - An Automated Energy Detection Algorithm Based on Morphological Filter Processing with a Semi-Disk Structure | U.S. Army Research Laboratory

摘要

This report is the result of applying morphological image and statistical processing techniques to the energy detection scenario of signals in the RF spectrum domain. A semi-disk structure is applied to the spectral data to estimate the envelope of the spectral response in the frequency domain. A morphological opening operation is then applied to the spectral envelope to obtain some measure of the background noise. These series of techniques provide for an automatic algorithm for determining the RF spectral threshold detection level.
