Implementation and Performance Analysis of Efficient Wireless Channels in WiMAX Using Image and Speech Transmission

This paper presents the simulation and performance analysis of WiMAX (Worldwide Interoperability for Microwave Access) system along with efficient wireless channels using real time image and speech transmission. WiMAX is the commercialization of the IEEE 802.16 standard, an evolving standard initiated at the National Institute of Standards and Technologies in 1998 before being transferred to the IEEE to form Working Group 802.16. WiMAX´s attributes open the technology to a wide variety of applications with its large range and high transmission rate. However, to complement the existing WiMAX system with highest transmission rate, the error rate possessed by the same must be as low as possible. Present status of traditional WiMAX has been modeled by many researchers. This paper enhances the current status of WiMAX system along with modeling of suitable wireless channels i.e. AWGN, Rayleigh, Rician, etc. so as to control BER of the system. Further with the variations of different channel parameters for image and speech transmission through WiMAX system, the structure compatible to practical scenario can be implemented through this modeling using antenna diversity principles along with suitable wireless channels so as to control BER of the system. As a whole the simulation results of this paper will enable the researchers to understand the concept of WiMAX system modeling with the finest selection of various types of wireless channels under appropriate circumstances.
