Abstract :
In this paper we present an LTE RAN (radio access network) emulator based on a new method for mobile channels modeling. The new method is then used to model the OFDMA downlink of LTE (long term evolution) link level performance under 16-QAM hierarchical modulation. The models have been derived for a quality of service (QoS) corresponding to a block error rate (BLER) of 1%, which is the common value for real-time applications. The results provided by the RAN Emulator are then compared to the statistical distribution of the received sequence in a LTE link level simulation. Further, we presented an analysis of the delay in a LTE transmission with different sources.
