Abstract
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
