Abstract :

Widespread employment of broadband networks, have been widely excited researchers and producers to develop and optimize this type of networks. This process is not possible, without study and deep preciseness in designing and type of the implementation of system. Recently introducing Worldwide Interoperability for Microwave Access (WiMAX) in communication world is invigorating researchers to devote their attempts in way of optimizing this favorite broadband networks. So in this paper, the possibility of transmission and regeneration of information and video pictures with acceptable signal to noise ratio(SNR) and bit error rate(BER) is provided by simulating physical layer of WiMAX system according to the IEEE 802.16-2004 standard. This simulation is done with MATLAB software and designed for approaching to appropriate quality and throughput in WiMAX networks. Simulation results shows that how video file in 'avi' format have been regenerated with an admissible quality after transmission in virtual designed space based on standard tested with 2-PAM and 64-QAM modulation techniques, simulation also shows how we can use peak signal-to-noise ratio (PSNR) of pictures in adaptive modulation and coding (AMC).
