Radio Access Network Emulator for LTE

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.
