Abstract
Growing demands for bandwidth as well as mobility have led to several research projects which are investigating high speed wireless LANs and within ETSI BRAN a wireless LAN called HIPERLAN/2 is being standardized. Within HIPERLAN/2 it is foreseen to adapt the modulation and code rate to the conditions of the radio link. With six different combinations of modulation and code-rate, data rates from 6 to 54 Mb/s with different requirements on the C/I and different resilience against transmission errors are possible. In most approaches when simulating system performance under the influence of interference a high number of radio cells has to be simulated to gain reliable results for the innermost cells. This makes it necessary to use simplified models for the scheduling and the ARQ scheme as otherwise simulation times become too high. In this paper another approach is proposed which applies an iterative process and tries to model all interference as coming from only one interfering radio cell. This leads to a slight difference in the distribution of the interference vs the position in the radio cell but then it is possible to use a detailed model of the scheduling, the ARQ scheme and the collision resolution in each iteration as well as mobility and realistic traffic models. Two scenarios are considered and the feasibility of the new approach is shown analytically and by means of simulations for these two scenarios. The results are compared against previously published results for the same scenarios which were gained with a standard approach.
