| Carrier frequency synchronization is a crucial process in the implementation of orthogonal frequency division multiplexing (OFDM) systems. It is divided into two phases: acquisition and tracking. Although different techniques for different standards have been presented in the literature, this paper is the first one presenting a novel carrier frequency synchronization process for the new standard IEEE 802.16 (WiMAX). The paper justifies the chosen techniques and presents the results obtained for a QPSK signal constellation in a Rayleigh channel with additive white Gaussian noise (AWGN). Results show that the proposed approach maintains the Bit Error Rate (BER) within 2% of the value obtained from an offset-free system. | |
