DOWN LINK MINUTE TIME SYNCHRONIZATION ESTIMATING APPARATUS OF OFDM SYSTEM AND A METHOD THEREOF, CAPABLE OF TRACKING MINUTE SYNCHRONIZATION REGARDLESS OF SIGNAL TO NOISE RATIO OF A RECEIVED SIGNAL IN A RAYLEIGH FADING CHANNEL

摘要

PURPOSE: A down link minute time synchronization estimating apparatus of OFDM system and a method thereof are provided to enhance the stability by minimizing a frame which causes a blank in a down link communication.;CONSTITUTION: A cross correlation part(101) obtains an absolute value of the correlation value in a window section of the signal received from the base station as much as the predetermined search section. A maximum value detecting section(102) obtains the maximum value of the absolute value obtained above and the time index of the maximum value. An operation unit(103) computes the Peak-to-Average ratio of the mean value of the maximum value of the absolute value and absolute value.;COPYRIGHT KIPO 2010
