Abstract
An apparatus for wireless communication includes a processing system. The processing system is configured to estimate a power spectral density of a first signal. In addition, the processing system is configured to determine a normalized correlation detector between the estimated power spectral density and a known power spectral density of a second signal. Furthermore, the processing system is configured to determine whether the first signal contains the second signal based on the normalized correlation detector.
