Abstract

AbstractThis paper provides an overview and comparison of traditional and advanced Link-to-System (L2S) interface mappings used in system level simulations to evaluate link performance in terms of packet error rate (PER). An Actual Value Interface (AVI) as traditional L2S interface is compared with an Effective SINR Mapping (ESM) as advanced L2S interface. This comparison is able to highlight the main differences in prediction of multi-state channel performance effecting on final data throughput, delay of data packets and required CPU time. Furthermore, this paper proposes an improved version of AVI method in order to improve the accuracy of system performance estimation. The comparison results show that in case of multi-state OFDM system, highest accuracy is achieved with Mutual Information ESM (MIESM) method and relatively good accuracy with the exponential ESM (EESM) method.KeywordsSystem simulatorL2S interfaceEESMMIESMAVIOFDM
