Abstract :
Orthogonal frequency division multiple access (OFDMA) is one of the modulation technique designed to have high speed data rate transmission in wireless communication system. Inter symbol interference (ISI) is a main cause that can reduce efficiency of the system due to multipath propagation. Different equalization of adaptive algorithm technique had been proposed in this research in order to reduce ISI in OFDMA system. This research also proved the combination of space time frequency block code (STFBC) with multiple input multiple output (MIMO) antenna enable to overcome ISI by using IEEE 802.16 simulation parameter. The simulation results show the improvement of bit error rate (BER) performance after reducing ISI and also prove that STFBC was able to achieve maximum diversity order in the MIMO OFDMA system.
