Abstract:
The objective of this thesis is a study of the standard 802.16 published by the Institute of
Electrical and Electronics Engineers where centric study on analysis of the physical layer of
this standard, Through the use of various simulation systems to reach the concept and the way
and the nature of the work standard (2004-2005) 802.16 and its features for standards other,
which included thesis study of different types of modification and encoding approved by the
Foundation Electrical and Electronics Engineers subject to this standard, and study the effects
of different fading and their impact on the signal and study included also compared extensive
between two types of antennas mono transmitter and receiver with multicast mono reception
used in systems WiMAX and between transmission with burst-one and multinational, was
also addressed to the impact of the Cyclic Prefix and its impact on the rate of data
transmission, have also been studying the effectiveness of the use of adapter amendment and
coding on the system and At the rate of bit error to reach the best configuration in which you
can get the maximum productivity of the system and improve performance bit error rate.
These goals have been achieved through the use of analytical description of WiMAX and
create mathematical models and computer simulations Parameters for WiMAX networks.
After analyzing system is designed device launched by name calculator smart one version.
Where characterized by their high-control Adaptive Modulation and Coding taxable standard
802.16 at appropriate values allow users to deal with the network with maximum rates Instant
data commensurate with the channel for each user as work copied scripts to use graphics
user Interface program MATLAB.
