Abstract
Satellite scanning is an example of scanning a transmission spectrum, which relates to identifying satellite channels within a satellite broadcast spectrum. Rather than scanning the entire transmission spectrum at each possible combination of frequency and symbol rate, spectrum analysis may be performed over the transmission spectrum in order to determine an estimate of signal strength over the transmission spectrum in the frequency domain. The estimate of signal strength in the frequency domain can be used to identify candidate transmission channels (e.g. at frequencies where the signal strength is high). A targeted scan of the transmission spectrum can then be performed based on the identified candidate transmission in order to identify the transmission channels.
