  3. Abstract:
  4. Wireless broadband access has gained so much attention in recent years. IEEE 802.16d as a standard in this field has provided MAC layer and PHY layer specifications. It has adopted OFDM method for one of PHY specifications that uses 256 subcarriers. In this paper we verify the effects of subchannelization option in uplink, on bit error rates in 16QAM modulation. Simulation results show that considerable improvement is obtained using half of the subcarriers
