OFDMA uplink synchronization is an important and challenging task, as one OFDM symbol carries data for many users and the correction of one user's time and frequency offsets cannot be accomplished easily at the base station receiver. The correction to one user would misalign other initially aligned users. We present a novel frequency synchronization algorithm that is demonstrated as an enhanced scheme for in the uplink of multiuser OFDM systems in a multi-path environment
