In this talk, data-aided timing and frequency synchronization techniques for downlink OFDMA transmissions will be presented. We will start with the conventional downlink transmission case, in which a user synchronizes to a base-station, followed by the coordinated multi-point transmission case, in which a user synchronizes with multiple base-stations at the same time. We will also present the results obtained from the test-bed, developed for the implementation of the proposed algorithms.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003Cbr \/\u003EMalik Muhammad Gul received his B.E and M.S. in electrical engineering from the National University of Sciences and Technology in Pakistan in 2007 and 2009, respectively.
