Abstract	The paper presents a new method to provide simultaneous time and frequency offset estimation that operates in the frequency domain by analyzing the modulus and angle of a synchronization symbol. When compared to those estimators based on computational intensive time-correlations, the main advantage of the proposed estimator is in the hardware implementation. In the proposed method, no additional hardware is required, as the already existing FFT processor and the polar coordinates translator (typically a CORDIC processor) used for OFDM normal operation are reused in the synchronization phase. Simulation results are presented using different conditions and channel models showing a negligible decrease in performance when compared to other methods.
