Abstract:

The WiMAX (Worldwide Interoperability for Microwaves Access) is a promising technology which can offer high speed voice, video and data service up to the customer end. The development of 802.16 standards for BWA (Broadband Wireless Access) technologies was motivated by the rapidly growing need for high-speed, ubiquitous and cost effective access. The WiMAX can also be considered to be the main technology in the implementation of other networks like wireless sensor networks. Developing an understanding of the WiMAX system can be best achieved by looking at a model of the WiMAX system. This paper discusses the model building of the WiMAX physical layer using simulink in Matlab R2009a version. This model is a useful tool for BER (Bit Error Rate) performance evaluation for the real time audio data communication by the WiMAX physical layer, under different channel encoding rate, and digital modulation schemes and channel conditions, besides serving as a helpful resource for the students and the researchers who want to base their studies and research in the field of WiMAX. In this paper, transmitter and reciver model are simulated according to the parameters established by the standards, to evaluate the performance. Also convolution coding is used to improve the system performance. The performance analysis is being done by studying the bit loss and packet losses occurred during transmission over the channel.
