Abstract
Automatic frequency control is provided in a satellite-based spread spectrum radio communication system by employing a pilot signal as a frequency reference. A transmitter inserts the pilot signal at a null point in the power versus frequency spectrum of the transmitted spread spectrum signal in order to minimize bandwidth requirements and to avoid interference between the pilot signal and the transmitted data.
