摘要：Worldwide Interoperability for Microwave Access (WiMAX) provides wireless broadband to fixed and mobile terminals. In this paper, firstly performance evaluation of WiMAX system without channel estimation is carried out. Then a fuzzy logic based channel estimation technique is proposed. Channel estimation is used because amplitude and phase shift causes error in wireless channel. Finally, Performance evaluation of WiMAX system using channel estimation technique is done. Bit error rate performance for different modulation schemes is then compared. Results show that by using channel estimation technique, bit error rate for all adaptive modulation techniques are improved.
