Modulation and RS-CC rate specifications in WiMAX IEEE 802.16 Standard with MATLAB Simulink model

Abstract

The intensive use of broadband system leading to focusing of telecommunication development industries, which are characterized by high quality features. Forthisissue, high transmission abilities in a new technologies systems have been designed. the WiMAX concept were proposed where a wireless transmission infrastructure that allows a fast deployment as well as low maintenance costs. Based on the IEEE 802.16-2004 standard, in this paper an end-to-end baseband model of the physical layer of a wireless metropolitan area network (WMAN) have been implemented using MATALB Simulink, according to the IEEE® 802.16-2004 standard. Supporting all of the mandatory coding and modulation options. It also illustrates Space-Time Block Coding (STBC), an optional transmit diversity scheme specified for use on the downlink. it illustrates the use of digital pre-distortion, a technique for extending the linear range of a nonlinear amplifier. Also modulation sets have been changed and tested in the model to reduce running time and power consumption. Finally, measurements of Error vector magnitude EVM and modulation error ratio MER were performed.
