Telecommunication industries are highly concerned with the wireless
transmission of data which can use various transmission modes, from
point- to-multipoint links. It contains full mobile internet
access. Various applications have already been applied so far using
WiMAX, as alternative to 3G mobile systems in developing countries,
Wireless Digital Subscriber Line, Wireless Local Loop . IEEE
802.16e-2005 has been developed for mobile wireless communication
which is based on OFDM technology and this enables going towards
the 4G mobile in the future. In this thesis work, we built a
simulation model based on 802.16e OFDM-PHY baseband and
demonstrated in different simulation scenarios with different
modulation techniques such as BPSK, QPSK and QAM (Both 16 and 64)
to find out the best performance of physical layer for WiMAX
Mobile. All the necessary conditions were implemented in the
simulation according to 802.16e OFDMA-PHY specification. The noise
channel AWGN, Rayleigh fading, SUI, data randomization techniques,
FFT and IFFT, and Adaptive modulation is used for the whole
simulation procedure. Performance has been concluded based on BER,
SNR and Pe output through MATLAB Simulation.
