WiMAX (world interoperability for microwave access) continues its development to achieve high capacity services with large cell coverage. Although, users at the cell border achieves only poor signal to interference plus noise ratio (SINR) conditions due to the high amount of interference from neighboring cells. In Egypt the 3.5 GHz band is expected to be used for the IEEE 802.16e mobile WiMAX networks...
WiMAX (Worldwide Interoperability for Microwave Access) has the potential to impact all forms of telecommunications. In a fixed wireless communication, WiMAX can replace the telephone company's copper wire networks, the cable TV's coaxial cable infrastructure while offering Internet Service Provider services. In its mobile variant, WiMAX has the potential to replace cellular networks. However, it...
WiMAX systems are based on the IEEE 802.16-2004 and IEEE 802.16e-2005 standards which define a physical (PHY) layer and the medium access control (MAC) layer for broadband wireless access systems operating at frequencies below 11 GHz. Multiple-antenna techniques can be used to increase diversity and improve the bit error rate (BER) performance of wireless systems, increase the cell range, increase...
WiMAX top level SIMULINK model with all system details has been implemented for simulation purpose. This paper has focused on channel estimation with different interpolation approaches for fixed/mobile OFDM system with parameters from WiMAX standards. The Doppler shift had a greater impact on the relative performancebetween the different channel estimators and interpolation approaches. One of the...
