Abstract
Mobile WiMAX is emerging as a means for low cost reliable wireless broadband connection compared to traditional DSL cable. The system requirement of next generation mobile WiMAX is supposed to be based on IEEE 802.16 m which is still in letter ballot stage. This paper attempts to make in depth performance evaluation of Mobile WiMAX under various PHY parameters such as modulation and coding schemes (MCS), cyclic prefixes and different path-loss models. Moreover it also present an optimized adaptive modulation scheme that senses the SNR and adaptively switches to required MCS towards achieving the desired level of Quality of Service (QoS) and link stability. Simulation results show that dynamic adaptation of modulation and coding scheme based channel conditions can offer enhanced throughput, load, reduced delay, SNR and BER.
