Query: Ber Performance Analysis of WiMAX PHY Layer under different channel
  conditions   This paper gives an introduction on the IEEE 802.16 standard WIMAX or
Worldwide Interoperability for Microwave Access. The different parts give
details on the architectural specifications of WiMAX networks and also on the
working principle of WiMAX networks including its services provided. It also
provides brief descriptions on its salient features of this technology and how
it benefits the networking industry. A brief outline of the basic building
blocks or equipment of WiMAX architecture is also provided. This paper also
evaluates the simulation performance of IEEE 802.16 OFDM PHY layer. The
Stanford University Interim (SUI) channel model under varying parameters is
selected for the wireless channel in the simulation. The performance
measurements and analysis was done in simulation developed in MATLAB.
