Abstract

The Always Best Connected Systems (ABCS) philosophy, in which different access technologies coexist, allows the user to select at any time an appropriate network that is optimized for the current service. To study this scenario through simulations, it is needed that all simulators are system-level type. Regarding this point, Effective SNR Mapping (ESM) algorithms provide the link layer abstraction that is crucial for the system level simulation interface. In this paper we have used the Mutual Information Effective SNR Mapping (MIESM) algorithm for instantaneous-channel modelling, calibration and evaluation of the Link Level Interface in the WiMAX System 802.16e together with a realistic Mobile WiMAX simulator. Plenty of simulations were performed to evaluate different algorithms and the results show that MIESM gives higher accuracy than the rest of ESM methods.
