This paper proposes a method to counteract the effect of different frequency offsets of the users in a OFDMA uplink system with frequency selective Rayleigh fading channel. The multiple access interference is reduced by reconstructing and removing the interfering signals. This is done by accomplish Successive or Selective Cancellation. The paper analyzes the performance of these cancellation schemes assuming either ideal or estimated frequency offsets.
