METHOD AND APPARATUS FOR LOCATING DIGITAL CARRIER SIGNALS

摘要

In a receiver for receiving a carrier modulated with data, there is provided a method and apparatus for searching L-Band spectra for digital carriers within a mixed analog/digital environment. Carrier lock is used as a pre-filter prior to checking for final forward error correction lock. Additionally, when a valid signal has been acquired, the system frequency plan is downloaded to further refine the search.
