In this paper, the authors analyze performance of MIMO OFDMA system in downlink access for Worldwide interoperability for Microwave Access/Long Term Evolution (WiMAX/LTE) system. They design the OFDMA system and analysis the parameter antenna height, power variation and modulation technique to obtain a good quality signal. The motive is increase the throughput of the system and decrease the BER. By using the Grade Of Service (GOS) in Automatic Frequency Planning (AFP) and propagation model Anderson 2D free-space plus Reflection Multiple Diffraction (RMD).
