Abstract
A method and apparatus for performing time synchronization and an OFDMA receiver thereof are provided. The method preferably includes performing a differential phase correlation in a frequency domain based on one received sequence and one reference preamble and detecting an integer frequency offset based on a result of the differential phase correlation. The method and apparatus advantageously enable the use of one OFDM symbol to estimate ICFO and the use of a simple method to facilitate ICFO detection. Moreover, the performance of the integer frequency offset estimation becomes more robust in high noise and time-variant fading channels, with reduced hardware complexity.
