  • Apparatus, method, receiver, and computer readable medium for time synchronization offset compensation
    Patent number: 7839898
    Abstract: Provided are an apparatus, a method, a receiver, and a computer readable recording medium for time synchronization offset compensation. The apparatus includes an average time synchronization offset calculator, a reference clock frequency difference calculator, and a time synchronization offset compensator. The average time synchronization offset calculator calculates an average time synchronization offset between a phase reference symbol of a time-synchronization acquired frame and phase reference symbols of frames subsequent to the time-synchronization acquired frame. The reference clock frequency difference calculator calculates a reference clock frequency difference between a transmitter and a receiver. The time synchronization offset compensator compensates a time synchronization offset.
