摘要

In this paper capacity analysis for mobile WiMAX (IEEE802.16e standard) working in DL adjacent subcarrier permutation mode is investigated mathematically depending on the physical layer simulation results. These simulation results of physical layer dispose exact values for the number of best burst profiles (modulation and coding schemes (MCSs), link speeds) that candidate to carry MAC (Medium Access Control) payload in thelnteraational Telecommunication Union- Recommendation(ITU-R) mixed user multipath fading channel under the Quality of Service (QoS) requirements for video streaming applications.This approach for capacity analysis based on simulation results is proposed to overcome the lack of interests by other researches in the significant influence of the physical layer constraints on the MAC layer capacity calculations. However, it has been noticed that the majority of researches rely on assumptions considered somewhat far from the essentials that characterized the IEEE 802.16e standard.Moreover, this paper focused on the exact overhead calculations by taking into account all the significant overhead parameters (static and dynamic) in the MAC layer frame structure that effects the overall system capacity.
