Abstract
There is disclosed a system and method for recovering a recurring data segment synchronization pattern in the presence of an arbitrary phase rotation of a pilot carrier by detecting and compensating for the amount of the phase rotation. The system comprises a first synchronization pattern detector capable of receiving a real component of a complex signal and detecting a data segment synchronization pattern on the real component, and a second synchronization pattern detector capable of receiving an imaginary component of a complex signal and detecting a data segment synchronization pattern on the imaginary component. There is also disclosed a method for compensating a pilot carrier phase rotation comprising the steps of determining the angle of pilot carrier phase rotation present in a complex signal and rotating the pilot carrier signal through the same angle in the opposite direction. Methods are also disclosed for compensating signal gain in a complex signal in which pilot carrier phase rotation has occurred.
