APPARATUS FOR FRAME AND CARRIER JOINT SYNCHRONIZATION AND METHOD THEREOF

摘要

PURPOSE: A combination and synchronization device between a frame and a carrier wave and a synchronization method thereof are provided to maintain communication quality by simultaneously estimating synchronization of the carrier wave and a symbol time by using one preamble. CONSTITUTION: A transmission unit(100) transmits and generates a combination synchronization preamble by using a progression length generation unit. A reception unit(200) simultaneously estimates carrier waves by using a frequency deviation estimator. The frequency deviation includes a phase arrangement device which uses a part of a duplex correlator. The phase correlator rotates a phase when a calculated output value is located on a second area and a third area.
