Mobile WiMAX is today one of the potential technology choices for delivering mobile broadband access. Despite its potential, existing radio coverage calculations only relate to a low level physical data rate, rather than to the actual MAC (Medium Access Control) throughput, which is more meaningful from a user's perspective. We therefore elaborated on linking high level MAC throughput to low level...
For Mobile WiMAX, data rate and throughput figures are often presented in literature. However, the used calculation methods and the influence of the packet size on the data rate are often unclear. Therefore, we develop a new method in order to obtain more precise data rate figures at the MAC (Medium Access Control) layer. In this paper the common physical data rate and MAC data rate calculation method...
The goal of this paper is to investigate the performance of a mobile WiMAX system for various settings of its physical-layer parameters and for realistic propagation channels. For this, a physical layer model of IEEE 802.16e is developed in software. Different propagation channels are implemented, such as the Rayleigh channel and the SUI channel models. Moreover, a tapped delay line channel model...
