CODING METHOD FOR ESTIMATING CARRIER FREQUENCY ERROR

摘要

PURPOSE: A coding method for estimating a carrier frequency error is provided to easily correct a carrier frequency error without channel information using a space-time block coding. CONSTITUTION: A transmission diversity system in which a channel between transmission antennas and one reception antenna is a flat fading channel encodes a space-time block for estimating a frequency error. A code matrix is obtained through a space-time block coding of K numbers of reception information symbols and a code matrix(Dk+mk) in which a code matrix(Dk) is delayed by m blocks satisfies a certain condition.
