METHOD AND APPARATUS FOR TIME SYNCHRONIZATION OF DISTRIBUTED NODES OVER WIDEBAND HIGH FREQUENCY WIRELESS

摘要

PURPOSE: A method and apparatus for time synchronization of distributed nodes over a wideband high frequency wireless system are provided to modify a MAC interface clock through the maximum operation offset among calculated operation offsets. CONSTITUTION: A MAC scheduler calculates an operation offset through the confirmation of a receiving node clock and a transmitting node clock(520), and stores the maximum operation offset by comparing calculated operation offset with the stored operation offset. If the completion of data reception is sensed, the MAC scheduler applies an RX_EN as 0(524). If the reception of a super frame is completed, the MAC scheduler modifies a MAC interface clock(528,530).
