The main objective of this research to implement, and analysis of WiMAX model with different modulation and coding schemes, Adaptive Modulation and Coding (AMC) using OPNET network modeler. By expressing the different types of modulation and coding method that actually used in wireless broadband network like WiFi, WiMAX. And more complex modulation methods that can guarantee higher data rates and require less interference and good line of sight (LOS) to the access points. In addition this research helps in understanding the concept of link adaptation which holds the view of adaptive MCS and other channel adaption attributes. And implementing of an adaptive modulation and coding scheme using AMC profiles to uate the performance according to spectral efficiency.-The main objective of this research to implement, and analysis of WiMAX model with different modulation and coding schemes, Adaptive Modulation and Coding (AMC) using OPNET network modeler.
