Performance Evaluation of WiMAX System in Various Morphological Scenarios

In the recent years, the WiMAX cellular system has been greatly deployed worldwide as it can provide high data rate to mobile subscribers. However, a few works has been done to characterize the behavior of the WiMAX network in different deployment scenarios. In this paper, we investigate the performance of the WiMAX system in various morphological scenarios, namely, dense urban, urban, and sub-urban. Moreover, we evaluate the behavior of the WiMAX system with different environment parameters such as cell radius, penetration loss, and receiver antenna gain. For each WiMAX scenario, relevant set of performance criteria such as the spectral efficiency is evaluated via system level simulations (SLS). Finally, this paper provides understanding and insights on the main design parameters affecting the performance of WiMAX systems.
