Performance Enhancement of WiMAX System Using Adaptive Equalizer

Mobile WiMAX is a wireless networking system which provides wireless broadband to fixed and mobile terminals. In this paper, firstly performance evaluation of WiMAX system with channel estimation is discussed. Performance evaluation with channel estimation is used because amplitude and phase shift causes error in wireless channel. Finally, Performance evaluation of WiMAX system using adaptive equalizer technique is then carried out. Bit error rate performance for different modulation schemes is then compared. Results show that by using adaptive equalization technique, bit error rate for all adaptive modulation techniques are improved. The equalizer mitigates the effect of the wireless channel and allows subsequent symbol demodulation.
